Summary: Flink RocksDB statebackend memory leak issue
Key: FLINK-18712
URL: https://issues.apache.org/jira/browse/FLINK-18712
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Affects Versions: 1.10.0
Reporter: Farnight
When using RocksDB as our statebackend, we found it will lead to memory leak
when restarting job (manually or in recovery case).
How to reproduce:
# increase RocksDB blockcache size(e.g. 1G), it is easier to monitor and
reproduce.
# start a job using RocksDB statebackend.
# when the RocksDB blockcache reachs maximum size, restart the job. and
monitor the memory usage (k8s pod working set) of the TM.
# go through step 2-3 few more times. and memory will keep raising.
Any solution or suggestion for this? Thanks!
