[jira] [Updated] (FLINK-34693) Memory leak in KafkaWriter
[ https://issues.apache.org/jira/browse/FLINK-34693?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stefan Richter updated FLINK-34693:
-----------------------------------
Description:
KafkaWriter is keeping instances of {{TwoPhaseCommitProducer}} in Dequeue of closeables ({{{}producerCloseables{}}}). We are only adding instances to the queue (for each txn?), but never remove them so that the can be GC’ed.
From heap dump:
