Roman Khachatryan updated FLINK-25458:
--------------------------------------
Description:
Currently, changelog state-backend doesn't support local recovery. Thus,
recovery times might be sub-optimal.
Current period materialization would call state backend snapshot method with a
materialization id. However, current local state managment would rely on
checkpoint id as storing, confirming and discarding. The gap between them would
break how local recovery works.
was:
Current changelog state-backend implementation cannot work well with local
recovery enabled.
Current period materialization would call state backend snapshot method with a
materialization id. However, current local state managment would rely on
checkpoint id as storing, confirming and discarding. The gap between them would
break how local recovery works.
