Julius Michaelis commented on FLINK-18712:
------------------------------------------
[~yunta] , may I ask: are you still working on this?
If so, can I ask you to check that this bug indeed doesn't appear with
{{state.backend.rocksdb.memory.managed: false}}? I'd like to make sure that the
bug I'm seeing is really the same bug.
> 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
> Assignee: Yun Tang
> Priority: Critical
> Fix For: 1.12.0
>
>
> 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!
