**Issue Evaluation** Category: `enhancement` | Status: **Evaluated** **Feasibility:** Feasible **Scope:** Dashboard backend (new model + service + controller) + frontend (new audit modal component) **Compatibility:** Non-breaking — additive feature, no existing APIs affected. **Assessment:** The dashboard already models `TRANSACTION` as a `TopicType` and tracks `transactionState`/`transactionId` in trace nodes (`TraceNode.java`, `ProducerNode.java`). However, there is no dedicated audit module for hanging half-messages (prepared but uncommitted/un-rolled-back). The proposed `TransactionHalfMessageAuditService` would need to: 1. Query the broker's `HALF` queue via existing `RocketMQAdminClient` to enumerate uncommitted transaction messages. 2. Track check-retry counts — this data is available in `TransactionState` from the broker's `EndTransactionProcessor`. 3. Expose manual commit/rollback endpoints — these would delegate to `MQAdminExt`.`endTransaction()`. **Considerations:** - Manual commit/rollback from the dashboard is a **privileged operation** — it must be gated behind proper authorization (admin role check) and ideally require confirmation. - The broker must expose half-message enumeration APIs; verify that `selectOneMessageByOffset` or equivalent admin commands support the `HALF` topic filter. - Check-retry count tracking may require broker-side metrics exposure if not already available via `getConsumerRunningInfo` or similar. **Verdict:** Valid enhancement with clear operational value for transactional messaging deployments. Implementation complexity is moderate — the main challenge is broker-side half-message enumeration API availability. --- *🤖 Evaluated by github-manager (automated)* -- This is an automated message from the Apache Git Service.
