             Summary: Support native and incremental savepoints
                 Key: FLINK-25276
                 URL: https://issues.apache.org/jira/browse/FLINK-25276
             Project: Flink
          Issue Type: New Feature
            Reporter: Piotr Nowojski


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.
