Roman Khachatryan commented on FLINK-22889:
-------------------------------------------
Seems like the recent spike in faliures is related to Postgress as opposed to
Mysql previously.
Locally, I can see that the pool is of correct size but Postgress still keeps
connections open even if no tasks are running.
That might mean that the pool is not closed properly in case of failover.
I'll look further into it.
