First in a series of changes to log the fused stage name instead of the computationId. Fused stage name or SystemName is visible to users on the pipeline execution graph which makes it easier to understand.

can we rename DataflowWorkerLoggingMDC.setStageName to DataflowWorkerLoggingMDC.setSytemStageName or DataflowWorkerLoggingMDC.setFusedStageName?

Renamed to setSystemStageName and getSystemStageName to align with getSystemName() on MapTask and ComputationState.


writer.println("Active Keys: <br>");
for (ComputationState computationState : allComputationStates.get()) {
writer.print(computationState.getComputationId());

getComputationId here will be useful. Maybe add getSystemName in addition to computationId..
This is printed on debug capture and not visble directly to users.

Updated to print both computationId and systemName in the debug capture output.

…core worker states

- Rename DataflowWorkerLoggingMDC stageName methods to systemStageName per reviewer feedback.

- Log both computationId and systemName in MetricsDataProvider debug output.

Thank you for the review @arunpandianp! I have pushed a fixup commit addressing both review comments:

  1. Renamed DataflowWorkerLoggingMDC.setStageName and getStageName to setSystemStageName and getSystemStageName across the Dataflow worker codebase and test suites.
  2. Updated MetricsDataProvider to log both computationId and systemName in the active keys debug HTML output.

writeIfNotEmpty(generator, "thread", String.valueOf(record.getThreadID()));
writeIfNotEmpty(generator, "job", DataflowWorkerLoggingMDC.getJobId());
writeIfNotEmpty(generator, "stage", DataflowWorkerLoggingMDC.getStageName());
writeIfNotEmpty(generator, "stage", DataflowWorkerLoggingMDC.getSystemStageName());
