>                 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?
