--------------------------------
Summary: PublishGCPPubSub processor stop working and is stucked
when using Record Oriented mode
Key: NIFI-13927
URL: https://issues.apache.org/jira/browse/NIFI-13927
Project: Apache NiFi
Issue Type: Improvement
Affects Versions: 1.26.0
Reporter: Julien G.
Attachments: EXAMPLE.json, nifi.tdump
When using the PublishGCPPubSub processor with the Record Oriented mode the
processor will stay stucked. It won't processor any FlowFile. When the
processor is terminated the thread isn't released by the processor.
It FlowFile Oriented mode, it works fine.
It seems to be linked to how many records are in the FlowFile, becase when
having a single record in the FlowFile, it seems to have no issue (may be it
take more time to appear).
But if you start to have more records in the FlowFile, it won't work. To make
the processor works again you either need to restart the node or removing and
recreating the processor. But it's temporary, because it some point it will be
stucked again. When stucked the processor won't be unstucked even after days
(we had a processor stucked for 3 days straight).
You can find attached a thread dump when the processor was running and stucked,
and with ~10 threads not released . And you can also find an example that will
show the issue with a FlowFile of 500 records that instantly stucked in the
publish.
