Piotr Nowojski updated FLINK-25276:
-----------------------------------
Summary: FLIP-203: Support native and incremental savepoints (was:
FLIP-182: Support native and incremental savepoints)
> FLIP-203: Support native and incremental savepoints
> ---------------------------------------------------
>
> Key: FLINK-25276
> URL: https://issues.apache.org/jira/browse/FLINK-25276
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Checkpointing
> Affects Versions: 1.14.3
> Reporter: Piotr Nowojski
> Priority: Major
> Fix For: 1.15.0
>
>
> Motivation. Currently with non incremental canonical format savepoints, with
> very large state, both taking and recovery from savepoints can take very long
> time. Providing options to take native format and incremental savepoint would
> alleviate this problem.
> In the past the main challenge lied in the ownership semantic and files clean
> up of such incremental savepoints. However with FLINK-25154 implemented some
> of those concerns can be solved. Incremental savepoint could leverage "force
> full snapshot" mode provided by FLINK-25192, to duplicate/copy all of the
> savepoint files out of the Flink's ownership scope.
