----------------------------------
Hi [~lirui] Can you give me some advice？
> The checkpoint state of FLINKSQL is getting bigger and bigger
> -------------------------------------------------------------
>
> Key: FLINK-22806
> URL: https://issues.apache.org/jira/browse/FLINK-22806
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing, Runtime / State Backends
> Affects Versions: 1.12.0
> Reporter: YUJIANBO
> Priority: Major
>
> I have added the parameter ：
> 1、state.idle.duration: 3600,
> 2、state.checkpoints.num-retained:3
> 3、sql：select count(1), LISTAGG(concat(m,n)) from tabeA group a,b
> I set the checkpoint state for one hour, but the size of the folder directory
> /checkpoint/shared is still growing. I observed it for two days and guessed
> that there was expired data in the /checkpoint/shared folder that had not
> been cleared?
> What else can limit the growth of state？
