Summary by CodeRabbit

  • New Features
    • Progress updates are reported during data saving, source post-processing, finalization, and record-count retrieval.
    • Active tasks report their current status, and completed tasks are removed from the active-worker list, including after timeouts.
    • Logs show worker statuses when jobs complete, including jobs that do not update dependencies, improving visibility into concurrent pipeline activity.

Walkthrough

The change adds synchronized, thread-specific worker status tracking. Task and ingestion code update or clear statuses, and the orchestrator logs available statuses after each completed non-lazy job.

Explanation

Issue [#796] requests logging other worker statuses after each task finishes. TaskRunnerBase.runJobTasks waits for all parallel task futures with Future.sequence, and OrchestratorImpl.runJobs logs statuses only when it receives a completed-job event. The implementation therefore does not log status when one task finishes while another task in the same job is still running. WorkerStatusManagerSuite tests the registry, but not per-task reporting.

🟡 Minor · Move status logging outside the deferred dependency update. · OrchestratorImpl.scala:274-282

pramen/core/src/main/scala/za/co/absa/pramen/core/runner/orchestrator/OrchestratorImpl.scala:274-282
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Move status logging outside the deferred dependency update.

When enableMultipleJobsPerTable is enabled, two successful non-lazy jobs can run concurrently for the same output table. The first completion removes itself from runningJobs, detects the remaining job, and skips updateDependencyResolver. Because the status log is inside that method, the first completion produces no status snapshot.

Issue #796 requires logging after each task completion. It provides no exception for duplicate outputs. Keep the dependency-update condition unchanged and move the existing status-log block to the completion loop after that condition.

Suggested fix
         if (!hasAnotherUnfinishedJob || !isSucceeded) {
           updateDependencyResolver(dependencyResolver, finishedJob, isSucceeded, isLazy)
         }
 
+        if (!isLazy) {
+          val statuses = WorkerStatusManager.getStatuses
+          if (statuses.nonEmpty) {
+            this.synchronized{
+              log.info(s"${Emoji.HAMMER_AND_WRENCH} Statuses of other workers:")
+              statuses.foreach { status =>
+                log.info(s"Thread ${status.threadId}: $status")
+              }
+            }
+          }
+        }
+
         state.addTaskCompletion(taskResults)

Remove the same block from updateDependencyResolver.

🟡 Minor · Register the status on the timeout worker thread. · TaskRunnerBase.scala:152-183

pramen/core/src/main/scala/za/co/absa/pramen/core/runner/task/TaskRunnerBase.scala:152-183
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Register the status on the timeout worker thread.

ThreadUtils.runWithTimeout executes the callback on a new ThreadWithException. The current registration runs on the caller thread, and the outer finally can clear that status after the timeout method returns. If the callback remains alive after interruption and cleanup, the orchestrator can log a completed task while its worker is still running.

Register the status inside the callback. Register it on the caller thread only for the direct-execution branches.
