Pierre Villard updated NIFI-6701:
---------------------------------
Status: Patch Available (was: Open)
> PublishGCPPubSub does not send all messages
> -------------------------------------------
>
> Key: NIFI-6701
> URL: https://issues.apache.org/jira/browse/NIFI-6701
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.9.2
> Reporter: Jake Dalli
> Priority: Major
> Labels: easyfix
> Time Spent: 50m
> Remaining Estimate: 0h
>
> I have found an issue with the PublishGCPPubSub processor. After
> implementing a number of flows, I have realised that approximately 30% of
> messages are sporadically not sent to Pubsub in spite of a 'Send Successful'
> response from the processor.
>
> Upon investigating the code on github
> ([https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-gcp-bundle/nifi-gcp-processors/src/main/java/org/apache/nifi/processors/gcp/pubsub/PublishGCPubSub.java|https://slack-redir.net/link?url=https%3A%2F%2Fgithub.com%2Fapache%2Fnifi%2Fblob%2Fmaster%2Fnifi-nar-bundles%2Fnifi-gcp-bundle%2Fnifi-gcp-processors%2Fsrc%2Fmain%2Fjava%2Forg%2Fapache%2Fnifi%2Fprocessors%2Fgcp%2Fpubsub%2FPublishGCPubSub.java]),
> I found the following issue:
> # On line 163 we get the Future for the 'Publish message' action.
> # On line 165 we have the following loop:
> {code:java}
> while (messageIdFuture.isDone()) {
> Thread.sleep(500L);
> }
> {code}
> This means that if the future isDone method returns, the thread sleeps. It is
> unclear to me why this is the case and I believe this is a bag, in my opinion
> the processor should sleep if the future is not done, thus the loop should
> read:
> {code:java}
> while(!messageIdFuture.isDone()){ ... }{code}
>
