Summary
This is a substantial implementation of RIP-2: Proxy Admin Standardized Management Interface — a dedicated gRPC admin server on the Proxy, isolated from the data-plane MessagingService. The PR adds ~6,400 lines across 34 files, including two gRPC services, a fine-grained ACL 2.0 auth interceptor, metrics, route event streaming, and comprehensive tests.
The architecture is well-thought-out: the admin server reuses the data plane's GrpcChannelManager/GrpcClientSettingsManager for online client visibility, the auth interceptor maps every RPC to a dedicated proxy.admin.* resource with least-privilege actions, and the kill switch (proxyAdminEnabled) provides a global off-ramp.
Given the size of this PR, I'm providing a high-level review focused on architectural concerns rather than line-by-line. Below are specific findings worth addressing.
Findings
-
[Warning]
ProxyAdminAuthInterceptor.java— Unmapped methods bypass authorization. TheMETHOD_PERMISSIONSmap is checked withif (resourceAction != null && ...), meaning any new RPC method added to the admin services that isn't explicitly mapped will silently skip authorization. Consider adding a fail-closed default: if a method is not in the map and auth is enabled, reject withPERMISSION_DENIEDrather than allowing it through. This prevents accidental exposure if a new RPC is added without updating the permission map. -
[Warning]
ProxyAdminAuthInterceptor.java:resolveSourceIp— The cast toInetSocketAddresscould fail for non-IP transports (e.g., Unix domain sockets). Thetry/catch(Throwable)handles it, but consider an explicitinstanceofcheck for clarity and to avoid masking unexpected errors. -
[Info]
ProxyStartup.java— The admin server sharesGrpcChannelManagerandGrpcClientSettingsManagerwith the data plane. This is correct for visibility but creates a tight coupling. The shutdown order inPROXY_START_AND_SHUTDOWNshould ensure the admin server shuts down before the data plane's channel manager, otherwise in-flight admin queries could NPE on a closed manager. -
[Info]
ProxyAdminServiceGrpcService.java— TheSubscribeRouteEventsserver-streaming RPC holds aStreamObserveropen indefinitely. Consider adding a max-lifetime or heartbeat mechanism to detect stale connections (e.g., if the client disappears without sendingRST_STREAM). TheRouteChangeNotifiershould also bound the number of concurrent subscribers to prevent resource exhaustion. -
[Info]
ProxyAdminConfigSupport.java—UpdateProxyConfighot-updates the proxy configuration at runtime. Ensure that the config update is atomic (or at least consistent) — if multiple fields are updated simultaneously, a reader could see a partially-updated config. Consider using a write-lock or immutable config snapshot pattern.
Suggestions
- The PR would benefit from being split into smaller, reviewable chunks (e.g., proto definitions + auth interceptor as one PR, service implementations as another, metrics as a third). This makes review more thorough and reduces risk.
- The RIP-2 design docs (
docs/rip-2-proxy-admin.md,docs/rip-2-least-privilege.md) are excellent. Consider linking them from the mainREADME.mdor adocs/INDEX.mdfor discoverability. - The test coverage is comprehensive (5 test files, ~1,600 lines of tests). Well done.
Cross-repo Note
This PR introduces new proto definitions (ProxyAdminService, AdminGrpc). If these protos are published to rocketmq-apis or a shared proto repo, ensure the corresponding client SDK changes (e.g., in rocketmq-clients) are coordinated.

Summary
Re-review after new commits. The architecture remains sound, but CI is failing on multiple compilation checks (maven-compile, bazel-compile, calculate-coverage) and the warnings from my previous review are still present.
CI Status
Multiple CI checks are failing:
maven-compile(ubuntu/macos/windows, JDK-8) — failurebazel-compile(ubuntu-latest) — failurecalculate-coverage— failureCodeQL-Build— failure
These need to be resolved before merge.
Previous Warnings (Still Present)
-
Auth interceptor fail-open:
ProxyAdminAuthInterceptor.javastill allows unmapped methods through whenresourceAction == null. If a new RPC is added without updatingMETHOD_PERMISSIONS, it bypasses authorization. Consider fail-closed behavior. -
SubscribeRouteEvents unbounded: No max-lifetime or subscriber limit on the streaming RPC. A client could hold the stream open indefinitely or spawn many subscribers.
-
Config update atomicity:
UpdateProxyConfighot-updates at runtime without visible synchronization. Concurrent readers could see partially-updated state.
Recommendation
Fix the CI failures first, then consider the architectural warnings. The code quality and test coverage are good overall.

Summary
This PR implements RIP-2: Proxy Admin Standardized Management Interface — a dedicated, independent gRPC Admin service on the RocketMQ Proxy with fine-grained ACL 2.0 authorization. The implementation is well-architected with strong security fundamentals.
Key Strengths:
-
Security-first design: Fail-closed authentication model, least-privilege ACL mapping with per-method resource/action pairs, and a global kill switch (
proxyAdminEnabled). The admin server intentionally avoids exposing channelz/proto reflection to minimize attack surface. -
Clean architecture: The admin server correctly reuses the data plane's
GrpcChannelManagerandGrpcClientSettingsManager, ensuring online clients are visible to admin queries without duplicating state. -
Cluster-wide aggregation: The
ProxyAdminPeerClientfan-out design is robust — peer failures are gracefully handled (skipped with warning logs) and never fail the aggregated call. Client deduplication byclient_idwith local-node-wins semantics is correct. -
Comprehensive test coverage: Auth interceptor tests verify permission mapping, privilege separation, and resource scoping. Service tests cover pagination, cursor stability under churn, and tampered cursor handling.
-
Good observability: Route change detection via
RouteChangeNotifierwith server-streaming provides real-time topology updates for control-plane consumers.
Minor Observations (non-blocking):
-
Default port 8083: The
adminGrpcPort=8083default could conflict with other services in some environments. Consider documenting this clearly in deployment guides. -
Peer fan-out timeout: The 3-second
proxyAdminPeerTimeoutMillisis reasonable, but under high load with many peers, verify this doesn't saturate the gRPC thread pool. Consider adding metrics for peer query latency/failure rates. -
Auth default:
proxyAdminRequireAuth=falsemeans the admin surface follows cluster-wide auth settings. When cluster auth is off, the admin surface is open. Worth emphasizing in security documentation. -
Debugging without reflection: The intentional absence of channelz/proto reflection is good for security, but operators may need guidance on debugging admin RPCs.
Overall: Solid, production-ready implementation of RIP-2. The security model is sound, the architecture is clean, and test coverage is comprehensive.

The adminSendMessage method hardcodes queue selection to getQueues().get(0) (always the first queue). For a production admin tool, consider using a proper queue selection strategy (e.g., round-robin or hash-based) to distribute admin messages across write queues. Sending all admin messages to queue 0 could create a hot-spot on that queue.

Error messages from internal exceptions are forwarded directly to clients via t.getMessage(). This could leak internal implementation details (class names, stack traces, config paths). Consider wrapping with a generic error message and logging the full exception server-side (which is already done via log.warn).

In getProxyRuntimeStats, the code iterates grpcChannelManager.getClientChannels() once to count by version and then calls .size() separately. Since getClientChannels() likely returns a snapshot, this is fine, but you could combine both passes into a single iteration for efficiency.

changeLogLevel changes the ROOT logger level, which affects the entire proxy process. This is quite coarse-grained. Consider supporting an optional loggerName parameter so operators can adjust specific logger levels (e.g., only RocketmqProxy or Remoting) without affecting global verbosity.

Summary
Re-review after 15 new commits (2026-09-08). The PR has been significantly updated with build system fixes, CI stabilization, authorization refactoring, and extensive test coverage additions. All CI checks are now passing.
Key Changes Since Last Review
Build System (submodule-based proto generation)
- Switched from unpublished
rocketmq-protoartifact torocketmq-apisgit submodule — this is the correct approach since the proto definitions are now versioned in the submodule - Bazel
maven_installaligned withrocketmq-proto 2.2.0/protobuf 3.24.4/ gRPC 1.50.0 - CodeQL build fixed with explicit Maven build + JDK 9+ for proto compilation
Authorization Refactoring (DefaultAuthorizationContextBuilder)
- Added support for many new request types (CheckClientBody, CreateTopicListRequestBody, LiteSubscriptionCtlRequestBody, etc.)
- Heartbeat handling improved: now creates sub-contexts per group for consumer heartbeats, rejects producer heartbeats with group
- Removed
isConsumerClientTypehelper — logic moved inline with more specific checks
New AuthorizationCompatibility layer
- Handles edge cases: producer-only heartbeats, unregisters without group, end-transaction without topic
- Defensive try-catch pattern for safe fallback
ConsumerFilterManager refactoring
- Added per-consumer-group
SubscriptionFilterHandlermap — cleaner separation of concerns - Topic config validation before registering filters
MQClientInstance constructor
- Wrapped initialization in try-catch — defensive but the catch block only logs; consider whether partial initialization state could cause issues downstream
Findings
- [Positive] Test coverage is excellent — 1000+ lines of new tests covering auth, pop consumer, orderly consumption, admin processor, etc.
- [Positive] Build system changes are well-structured and all CI checks pass
- [Positive]
AuthorizationCompatibilityis a clean way to handle edge cases without polluting the main authorization flow - [Warning]
MQClientInstanceconstructor catch block — swallowing exceptions during initialization can mask real failures. IfMQClientAPIImplconstruction fails, the instance is in a partially initialized state. Consider re-throwing or at least marking the instance as failed. - [Info]
DefaultAuthorizationContextBuildernow has many imports — consider whether the class is becoming a god-class and if some request-type handling could be delegated to strategy classes
CI Status
All checks passing: CodeQL, bazel-compile, calculate-coverage, check-license, maven-compile (all platforms), misspell-check.

Implement the RIP-2 control-plane admin capability as a gRPC service served from the proxy process (NOT connecting to broker remoting/grpc directly), per the rocketmq-apis admin.proto contract. - Add ProxyAdminGrpcService serving all 16 RIP-2 Admin RPCs (v2-only, no org.apache.rocketmq.remoting import in the gRPC layer) - Add AdminModelConverter as the sole v2<->remoting bridge - Add DefaultAdminService broker gateway via proxy-owned MQClientAPIExt - Vendor apache.rocketmq.v2 generated proto sources into proxy/src/main/java so the proxy builds standalone - Add ProxyAdminGrpcServiceTest (21 cases) covering all RPCs + errors - Make GrpcConverter.buildMessage null-safe for synthetic MessageExt
…2 sources Switch the proxy RIP-2 admin implementation from vendored apache.rocketmq.v2 generated sources (committed under proxy/src/main/java/apache) to a proper Maven dependency on org.apache.rocketmq:rocketmq-proto:2.3.0. That artifact is built locally from the rocketmq-apis submodule (java/VERSION = 2.3.0) and provides the RIP-2 admin proto classes (VerifyMessage, AdminSendMessage, ChangeLogLevel, DescribeGroupAccumulation, ListSubscription, etc.). - Remove the 225 vendored apache/rocketmq/v2/*.java files - Restore rocketmq-proto dependency in proxy/pom.xml at version 2.3.0 - Bump root pom <rocketmq-proto.version> to 2.3.0 so all modules converge (fixes the enforcer dependency-convergence error) - Full proxy unit tests (324) still pass with no regression
Implement ListClients, DescribeClient, ListClientsByGroup, ListClientsByTopic in a new ProxyAdminServiceGrpcService, backed by the proxy's own GrpcChannelManager + GrpcClientSettingsManager (read-only, no broker remoting). - Add connect-time tracking to GrpcClientChannel - Register ProxyAdminServiceGrpcService in ProxyStartup admin gRPC server - Add unit tests: ProxyAdminServiceGrpcServiceTest (7), extend AdminModelConverterTest and DefaultAdminServiceTest Note: pom.xml (rocketmq-proto 2.3.0) intentionally not committed per request.
Finish every RIP-2 requirement that the gap audit found missing on this branch, keeping the admin layer protocol-pure on the rocketmq-apis generated contract (remoting types stay in AdminModelConverter). rocketmq-apis submodule - register rocketmq-apis as a git submodule (feature/rip-2-proxy-admin-grpc) and pin the commit that carries the full ProxyAdminService proto contract - root pom rocketmq-proto.version -> 2.3.0, built from the submodule D2 dedicated proxy.admin.* ACL authorization - ProxyAdminAuthInterceptor: per-RPC (resource, action) mapping over six resources (client/config/connection/quota/route/ops); KickClient, DisconnectChannel, ResetGroupOffset, DeleteSubscription, AdminSendMessage are high-privilege (Update/Delete/Pub) and can never be authorized by read-only grants; fail-closed proxyAdminRequireAuth mode; audit logging Acceptance criteria - ProxyAdminMetricsManager/Interceptor: rocketmq_proxy_admin_rpc_total and rocketmq_proxy_admin_rpc_latency (RT + error rate per method) - docs/rip-2-proxy-admin.md (RIP proposal) and docs/rip-2-least-privilege.md (least-privilege guide) M1 hardening - DescribeClient now reports real heartbeat history and auth status (tracked on GrpcClientChannel via heartbeat/telemetry hooks in ClientActivity) plus best-effort Pop/consume progress aggregated across all brokers of each subscribed topic - D3 cluster aggregation: PROXY_SCOPE_ALL_PROXIES fans out through ProxyAdminPeerClient to configured peer admin endpoints and merges the deduplicated view; local view stays the default - D4 pagination switched to a stable clientId cursor (base64-opaque next_token) so pages survive membership churn M2 surface (all 14 ProxyAdminService RPCs implemented) - DescribeProxyConfig/UpdateProxyConfig hot update with changed_fields - KickClient/DisconnectChannel with mandatory audit reason - DescribeQuota/UpdateQuota (mapped knobs apply to live ProxyConfig) - DescribePopReceiptHandles / DescribeBatchConsumeDiagnostics from the proxy's own receipt-handle tracking (read-only scan API) - SubscribeRouteEvents server-streaming (snapshot replay, broker online/offline, queue scaling, topic create/delete) via a TopicRouteService refresh listener; DescribeRouteTopology Quality fixes from the audit - deleteSubscription is now real (broker-side deleteSubscriptionGroup on every broker hosting the topic) instead of an empty shell - multi-broker support for accumulation, offset reset and key-based message query (previously only the first broker of the route was used) - queryTimeSpan reports the real last-consume timestamp - admin server no longer exposes channelz/proto reflection; kill switch proxyAdminEnabled added Tests: 60+ admin unit tests (auth mapping & fail-closed modes, stable pagination, route events, config/quota) plus adapted existing suites; full proxy module green (373 tests) and checkstyle clean.
….3.0 The previous cleanup commit dropped .gitmodules but left the rocketmq-apis gitlink in the index and reverted rocketmq-proto back to 2.1.2, which cannot compile the RIP-2 admin code. Remove the leftover gitlink and restore rocketmq-proto.version to 2.3.0. rocketmq-apis stays a LOCAL-ONLY dependency: the 2.3.0 artifact is built from the rocketmq-apis checkout (feature/rip-2-proxy-admin-grpc) with its Maven packaging and installed into the local repository; the folder is not tracked by this repository.
…, drop custom ProxyAdminService surface The custom ProxyAdminService contract (proto 2.3.0 from the rocketmq-apis feature branch) is abandoned in favor of the upstream Admin service contract (rocketmq-proto 2.2.0 from rocketmq-apis main). - bump rocketmq-proto.version 2.1.2 -> 2.2.0 - remove ProxyAdminServiceGrpcService, ProxyAdminPeerClient, RouteChangeNotifier, ProxyAdminConfigSupport, ProxyAdminDiagnosticsSupport and their tests - revert RIP-2-only hooks in GrpcClientChannel (heartbeat history, auth username), ClientActivity, TopicRouteService (route refresh listener) and the receipt-handle diagnostics accessors - trim ProxyAdminAuthInterceptor to the 16 upstream Admin RPCs and drop the quota resource; prune dead AdminModelConverter methods - keep the dedicated admin gRPC server (adminGrpcPort=8083), ProxyAdminGrpcService (16 Admin RPCs), proxy.admin.* ACL mapping and the OTel RT/error-rate metrics RIP-2 M1 mapping on the upstream contract: ListClients(ByGroup/ByTopic) -> ListConsumerConnection(group[, topic]); DescribeClient -> DescribeSubscription + GetConsumerRunningInfo; multi-proxy -> local view per proxy.
Rework rip-2-proxy-admin.md / rip-2-least-privilege.md around the upstream Admin service (16 RPCs): dedicated admin port + ACL 2.0 proxy.admin.* mapping for the 16 RPCs, the M1 capability mapping and its documented boundaries (clientId-prefix filter, pagination and heartbeat/auth detail are out of scope for the upstream contract), and the local-view multi-proxy decision. Refresh rip-2-issue.md and rip-2-pr.md to describe the delivered state and the 2.2.0 build prerequisite.
Passing a null QueueSelector made every adminSendMessage RPC fail with NPE inside the producer pipeline (QueueSelector.select called on null). Select the first write queue of the topic route instead. Verified end-to-end: adminSendMessage now returns a real msgId and queryMessage by key finds the written message (write+read closed loop).
Upstream develop replaced fastjson (v1) with fastjson2, so the v1 import no longer resolves on the proxy module and CI compiles fail with 'package com.alibaba.fastjson does not exist'. Switch to fastjson2, whose JSON.toJSONString API is source-compatible for this usage.
rocketmq-proto 2.2.0 is generated with protobuf gencode 3.24.4, whose generated classes call LazyStringArrayList.emptyList() that is only public from 3.21+. With the repository pinned at protobuf-java 3.20.1 this fails at runtime with IllegalAccessError, e.g. DefaultAuthorizationContextBuilderTest.buildGrpcLiteSubscriptionIgnoresLiteTopics on the auth module (JDK8 CI). Align the runtime with the proto gencode. Verified on JDK8: full-repo compile/install BUILD SUCCESS, auth module 63 tests green (incl. the previously failing lite-subscription test), proxy module 352 tests green.
…obuf 3.24.4 The pom was bumped to rocketmq-proto 2.2.0 (RIP-2 admin rebase on the 2.2.0 contract) and protobuf 3.24.4, but WORKSPACE maven_install still pinned rocketmq-proto:2.1.2 and protobuf-java:3.20.1. Bazel therefore compiled proxy against the old proto jar, where the RIP-2 admin message types (ClientInfo, DescribeGroupAccumulationResponse, AdminSendMessageRequest, GetProxyRuntimeStatsRequest, ...) do not exist, failing //proxy:proxy with 'cannot find symbol'. Match the Maven side: rocketmq-proto 2.1.2 -> 2.2.0 and protobuf-java / protobuf-java-util 3.20.1 -> 3.24.4. rules_jvm_external has no lock_file, so the artifact list is the source of truth and resolves live.
rocketmq-proto 2.2.0 (parent rocketmq-client-java-parent 5.2.2) declares gRPC 1.50.0 transitively. With the WORKSPACE artifacts still pinned at 1.47.0, coursier fails dependency resolution with conflicting grpc-core / grpc-protobuf / grpc-stub versions (1.47.0 vs 1.50.0), so @maven cannot be fetched and every target depending on it fails to analyze. Bump all seven io.grpc.* pins (grpc-services, grpc-netty-shaded, grpc-context, grpc-stub, grpc-api, grpc-protobuf, grpc-testing) from 1.47.0 to 1.50.0 to match rocketmq-proto 2.2.0's gRPC version.
…f unpublished artifact The RIP-2 admin contract lives in apache/rocketmq/v2/admin.proto, which is not part of any rocketmq-proto artifact published to Maven Central (latest is 2.2.0). Previously the build resolved org.apache.rocketmq:rocketmq-proto from Central, so the proxy could not see the admin types. Pull apache/rocketmq-apis (main) in as a git submodule and generate the Java + gRPC classes from its .proto sources in a new in-reactor module, so the proto is consumed from source rather than from an unpublished Central artifact. No fabricated upstream version is introduced: the module inherits the project version like every other rocketmq module. - add rocketmq-apis submodule pinned to apache main (3e60073) - add rocketmq-proto module generating from the submodule protos - drop the external rocketmq-proto version pin; proxy/auth/test now depend on the in-reactor module - CI: checkout with submodules: true (maven/bazel/coverage/integration-test) - .bazelignore the submodule so bazel build //... does not attempt to build its targets, whose external deps are not declared in this workspace
…azel build The Bazel build resolved org.apache.rocketmq:rocketmq-proto from Maven Central, which has no artifact containing the RIP-2 admin contract (admin.proto), so //proxy:proxy could not see the admin types. Generate the protocol classes from the submodule instead, mirroring what the rocketmq-proto Maven module does. The submodule's own BUILD files pull in toolchains this workspace does not declare (graknlabs_bazel_distribution, googleapis), so the directory stays in .bazelignore and is surfaced as @rocketmq_apis via new_local_repository and a minimal build file. That keeps 'bazel build //...' from trying to build it. protoc and protoc-gen-grpc-java are fetched as prebuilt executables with http_file: rules_jvm_external can only resolve jar artifacts, and the grpc-java Bazel toolchain would build both from C++ sources. The well-known type protos come from the protobuf source archive, because the standalone protoc does not bundle them; their include dir must be on the protoc import path or definition.proto fails and every symbol it defines looks undefined. proxy, auth and test now depend on //rocketmq-proto:rocketmq-proto instead of @maven//:org_apache_rocketmq_rocketmq_proto.
- genrule must emit a .srcjar (java_library srcs rejects .jar), the pushed commit had the stale .jar output name - rocketmq-proto is 100%% generated code: skip the parent checkstyle validate execution (mirrors existing spotbugs.skip/javadoc.skip), the inherited generated*/excludes do not cover checkstyle scanning of target/generated-sources
skywalking-eyes header check flagged .bazelignore, .gitmodules, bazel/rocketmq_apis.BUILD and rocketmq-proto/BUILD.bazel as missing a license header. Add the same Apache-2.0 block used by the other Bazel build files in the repo.
AdminModelConverterTest imports com.alibaba.fastjson.JSON; Maven gets it transitively on the test classpath but Bazel strict deps need it declared explicitly in //proxy:tests.
rocketmq-proto generates Java from the rocketmq-apis git submodule at compile time; without submodules: true the CodeQL autobuild fails on the missing proto sources.
Upstream develop removed com.alibaba:fastjson from maven_install; follow the fastjson2 migration so the RIP-2 admin test does not depend on the dropped artifact.
The CodeQL autobuild fails to handle the rocketmq-proto module that generates Java from the rocketmq-apis submodule at compile time. Build explicitly with Maven instead, and upgrade the deprecated github/codeql-action v2 to v3.
The generated gRPC sources reference javax.annotation.Generated, which exists in the JDK 8 runtime but was removed from the JDK in 9. Add javax.annotation-api (provided) so the module compiles on newer JDKs, and pin the CodeQL build to JDK 8 like the other Maven workflows.
The in-flight message count decays to zero asynchronously with the consumer offset reaching the broker max offset, so asserting it immediately after the consumer lag reaches zero is racy under load. Poll the inflight stats with awaitility instead, consistent with the existing pattern in this test and the upstream flaky-test fixes.
- remove docs/rip-2-issue.md and docs/rip-2-pr.md: issue/PR text copies do not belong in the repository, and rip-2-pr.md still described the abandoned install-rocketmq-proto-2.2.0 flow - rip-2-proxy-admin.md: document the rocketmq-apis git submodule and the rocketmq-proto build-time generation (Maven module + Bazel genrule) instead of the outdated manual artifact installation
- add ProxyAdminMetricsManagerTest covering init across OTLP_GRPC (with/without target, delta/cumulative temporality, header parsing), PROM, LOG and disabled exporters, recordSuccess/recordError paths (including null error fallback) and shutdown idempotency - add ProxyAdminMetricsInterceptorTest covering OK and error close forwarding through the observed ServerCall - extend ProxyAdminGrpcServiceTest with failure and edge branches: missing route lookups, broker error aggregation for deleteSubscription/resetGroupOffset, multi-broker fan-out and deduplication, cross-broker key query continuation, null message skip, timestamp/maxNums handling, telemetry write failures, channel manager failures, clients without settings, admin send with optional fields and failed send futures - extend ProxyAdminAuthInterceptorTest with authentication failure (unique AuthConfig name to avoid evaluator caching), authorization without credentials fail-closed and open-mode pass-through

[P1] Normalize the transport channel ID before authentication
Server interceptors run in reverse registration order, so appending ProxyAdminAuthInterceptor here makes it execute before HeaderInterceptor. At that point, DefaultAuthenticationContextBuilder reads x-mq-channel-id directly from the inbound metadata, before it is replaced with the actual transport channel ID.
With StatefulAuthenticationStrategy enabled, authentication results are cached by channel ID + username. A request on another physical connection can therefore supply the same metadata ID and username, reuse a successful cache entry, and bypass signature verification.
I reproduced this locally against 0a2a49794d using the real gRPC interceptor chain and stateful authentication strategy with an in-memory signature-checking provider: connection A populated the cache with a valid signature; connection B used the same metadata channel ID and an invalid signature, but still reached the service handler (expected 1 invocation, actual 2). The relevant ordering and authentication code are unchanged in 1e68ca8932.
Please run HeaderInterceptor before authentication, or populate the authentication context's channel ID directly from the server call's transport attributes before evaluating it. This finding applies when stateful authentication is enabled; the default StatelessAuthenticationStrategy is not affected by this cache bypass.
Bind the upstream `Admin` service (apache/rocketmq/v2/admin.proto, all 16 RPCs)
on a dedicated, opt-in admin gRPC server on the proxy, isolated from the data
plane and gated by grpcAdminServerEnable (default off).
- Contract-honest implementation: every RPC either serves real data or answers
with an explicit status; fields the open-source proxy cannot supply
(GetProxyRuntimeStats in/out TPS, DescribeTopicStatus create_timestamp/tags,
gRPC v2 GetConsumerRunningInfo process/consume tables) are left unset with an
explanation instead of faked.
- Broker-facing RPCs go through an asynchronous AdminService gateway that fans
out to all relevant brokers concurrently, with a per-hop deadline so a slow or
unresponsive broker cannot hang the gRPC executor.
- Connection/subscription listings are cluster-visible: broker-side
ConsumerConnection (remoting + peer-synced clients) merged with the proxy's
ConsumerManager (local gRPC v2 clients), deduplicated by group+topic.
- Client-directed RPCs (PrintThreadStackTrace, VerifyMessage,
GetConsumerRunningInfo) relay to the owning client's telemetry stream and are
forwarded to the peer proxy that owns the client (ProxyAdminForwarder, guarded
by x-mq-admin-forwarded).
- AdminSendMessage honours system properties for timer/FIFO messages;
VerifyMessage relays the stored message body without re-inflating it.
- Dedicated proxy.admin.* ACL 2.0 resources with read-only / high-privilege
action separation and a per-RPC audit log. Fail-closed mode
(grpcAdminServerAuthEnable) requires both cluster authentication and
authorization to be enabled, refusing otherwise so the ACL is truly enforced.
- rocketmq-proto builds the v2 stubs from the rocketmq-apis submodule (Maven +
Bazel); the module skips Maven deploy.
- Config keys: grpcAdminServer{Enable,Port,AuthEnable,RequestTimeoutMillis}.
- Docs (docs/proxy-admin.md + docs/proxy-admin-zh.md) and unit tests.

[RIP-2] Implement Proxy Admin Standardized Management Interface on the Proxy
1. Summary
This PR implements RIP-2: Proxy Admin Standardized Management Interface — the upstream
AdmingRPC service (apache/rocketmq/v2/admin.proto, fromapache/rocketmq-apismain, artifactorg.apache.rocketmq:rocketmq-proto:2.2.0) bound by the RocketMQ Proxy on a dedicated admin gRPC server, isolated from the data-planeMessagingService, with fine-grained ACL 2.0 authorization under dedicatedproxy.admin.*resources.It closes the observability gap introduced by RocketMQ 5.0's stateless Proxy: gRPC clients attached to a Proxy are invisible to operations tooling that relies on broker-side
ConsumerManagerand Remoting-era admin commands. With this change the Proxy itself can answer "which SDK clients are online, what do they subscribe to, how far behind are they" through a stable, community-reviewed contract — which is exactly what RIP-1 (Control Plane 5.0 dashboard, requirementCLIENT-01) depends on.Contract choice: upstream
Admin, not a bespokeProxyAdminServiceAn earlier draft of this work defined a custom
ProxyAdminServiceon a local rocketmq-apis feature branch. That surface has been removed. The control plane now consumes the same versioned, community-reviewedadmin.protothat the dashboard and the multi-language SDKs already use, so there is no forked API evolution and the implementation stays additive-compatible with upstream proto changes. The only protocol-level change in this repo is the artifact version bump (rocketmq-proto2.1.2→2.2.0inpom.xml); therocketmq-apisrepository is intentionally not vendored or submoduled here.2. What This PR Adds
2.1 Dedicated admin gRPC server (control plane)
ProxyStartupstarts a second gRPC server on its own port (adminGrpcPort, default 8083), with its own interceptor chain (metrics → auth → standard pipeline), separate from the data plane (8081).Key design point: the admin server reuses the data plane's
GrpcChannelManager/GrpcClientSettingsManager. Without that sharing, admin queries would read an always-empty, isolated channel map andListConsumerConnection/DescribeSubscriptionwould perpetually return nothing.GrpcMessagingApplication#getGrpcMessagingActivity(),DefaultGrpcMessagingActivity#getGrpcChannelManager(),#getGrpcClientSettingsManager(),GrpcChannelManager#getClientChannels()andDefaultMessagingProcessor#getServiceManager()are the (additive) accessors added for this purpose.The admin port intentionally does not expose channelz or proto reflection — the control-plane attack surface is kept minimal. A global kill switch
proxyAdminEnableddisables the whole surface.2.2
ProxyAdminGrpcService— all 16AdminRPCs on the ProxyProxyAdminGrpcService extends AdminGrpc.AdminImplBaseand serves every RPC of the upstreamAdminservice.

Several admin operations were initially single-broker and returned incomplete results on multi-broker clusters. This PR fixes that with
resolveBrokerAddrs(topic)(all distinct broker addresses of the topic route, order-preserving) plus:ResetGroupOffsetresets on every broker hosting the topic, aggregating per-broker errors instead of failing on the first one.DeleteSubscriptionfans out to every broker and reports partial failures.QueryMessageby message key searches brokers untilmaxNumsmessages are collected (a key may live on any broker).AdminModelConverter#toGroupAccumulationMultiBrokeraggregatesConsumeStatsacross brokers, deduplicating byMessageQueueso queues are never double counted.QueryTimeSpanreports the real last-consume timestamp from the offset table (falling back tominStoretimefor never-consumed queues) and resolves per-queue broker addresses for the store-time lookup.2.3
proxy.admin.*ACL 2.0 authorizationProxyAdminAuthInterceptormaps every RPC to exactly one(resource, action)pair across five dedicated resources:proxy.admin.clientListSubscription,ListConsumerConnection(List);DescribeSubscription,DescribeGroupAccumulation,GetConsumerRunningInfo,QueryTimeSpan(Get)proxy.admin.configChangeLogLevelproxy.admin.connectionPrintThreadStackTrace,VerifyMessageproxy.admin.routeGetTopicRouteproxy.admin.opsGetProxyRuntimeStats,DescribeTopicStatus,QueryMessage(Get);ResetGroupOffset(Update);DeleteSubscription(Delete);AdminSendMessage(Pub)Modeling note: ACL 2.0 resource types are cluster / namespace / topic / group. The admin resources are modeled as CLUSTER-typed literals with reserved names (
cluster:proxy.admin.<module>), which yields exact least-privilege matching, cannot collide with real cluster names, and requires no change to the auth core engine.Behavior modes:
proxyAdminRequireAuth=false→ open surface (identical semantics to the data plane);Authorizationmetadata;proxyAdminRequireAuth=true→ fail-closed: requests without verifiable credentials are rejected (UNAUTHENTICATED) even when the cluster-wide switch is off.High-privilege RPCs (
ResetGroupOffset,DeleteSubscription,AdminSendMessage,PrintThreadStackTrace,VerifyMessage) can never be authorized by a read-only grant. Every served RPC emits an audit record[PROXY-ADMIN-AUDIT] subject | method | resource | action | sourceIpon the RocketMQ auth audit logger, completing the required four-tuple (Console user + AK + resource + operation).2.4 Observability
ProxyAdminMetricsManager/ProxyAdminMetricsInterceptorexport two OpenTelemetry instruments, reusing the proxy's existing metrics exporter configuration (OTLP gRPC / Prometheus / logging):rocketmq_proxy_admin_rpc_total{rpc_method, status, error_type?}— error rate =rate(status="error")rocketmq_proxy_admin_rpc_latency{rpc_method, status}(ms histogram) — RT P50/P99Transport-level failures (auth rejection, permission denial, framework errors) are recorded by the interceptor; business-level failures are recorded by the service. The Prometheus reader binds
metricsPromExporterPort + 1to avoid colliding with the data-plane endpoint.2.5 Protocol-pure layering
AdminModelConverteris the only class importing both the broker's internal wire types (org.apache.rocketmq.remoting.*) and the gRPC protocol (apache.rocketmq.v2.*). The gRPC admin service stays protocol-pure (v2 only), and the broker gateway (DefaultAdminService) stays remoting-pure — neither layer leaks into the other.2.6 Multi-proxy semantics: local view (RIP-2 M1)
Each proxy answers from its own state and returns the local view only — the "local view" option explicitly allowed by RIP-2 M1. A dashboard that needs a cluster-wide picture queries every proxy's admin endpoint and merges by
client_id(a gRPC client is attached to exactly one proxy at a time). This keeps the protocol free of scope/peering fields and the proxy free of membership configuration; the earlier draft's peer fan-out (proxyAdminPeerEndpoints) was dropped together with the bespoke contract it served.3.

RIP-2 M1 Capability Mapping & Known Boundaries
ListConsumerConnection(group[, topic])DescribeSubscription+GetConsumerRunningInfoListConsumerConnection(group[, topic])Also out of scope (need upstream proto evolution): Remoting-client coverage in
