[jira] [Created] (FLINK-11748) Optimize savepoint: Remove the task states and KeyedState into increments.

Mr.Nineteen created FLINK-11748:
-----------------------------------

             Summary: Optimize savepoint: Remove the task states and KeyedState into increments.
                 Key: FLINK-11748
                 URL: https://issues.apache.org/jira/browse/FLINK-11748
             Project: Flink
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.7.2, 1.6.4, 1.6.3
            Reporter: Mr.Nineteen
             Fix For: 1.8.0


The optimized savepoint (v3) comes from the blink branch. After verification, I want to merge into the main branch of flink. For large jobs, the storage space for savepoints is significantly reduced. This optimization will be great in the next flink release.
