<!-- code-pr-reviewer --> This is a valid documentation improvement task. The `SinkFlowLifeCycle` class (seatunnel-engine/seatunnel-engine-server/src/main/java/org/apache/seatunnel/engine/server/task/flow/SinkFlowLifeCycle.java) currently lacks Javadoc for its core methods, which is important for contributors understanding the Zeta engine's checkpoint and barrier alignment mechanisms. A few clarifications from the codebase: 1. **`init()`** (lines 148-153) initializes serializers and the committer, but writer creation/restore actually happens in `restoreState()` (lines 325-350), not `init()`. The Javadoc should reflect this accurately. 2. **`received(Record<?>)`** (lines 191-306) handles three types: barriers (triggering `prepareCommit()` and snapshot), `SchemaChangeEvent`, and data records (calling `writer.write()`). This is the core data flow entry point. 3. **`close()`** (lines 173-177) calls `super.close()`, then `writer.close()`. Note that the current implementation does not call `committer.close()`, contrary to what the issue description suggests. 4. **`triggerBarrier(Barrier)`** is referenced in the issue, but the actual barrier handling logic is inlined within `received()`, not a separate method. The task is suitable for new contributors. Please run `./mvnw spotless:apply` after adding Javadoc to ensure formatting compliance. -- This is an automated message from the Apache Git Service.
