[jira] [Created] (FLINK-6364) Implement incremental checkpointing in RocksDBStateBackend

Xiaogang Shi created FLINK-6364:
-----------------------------------

             Summary: Implement incremental checkpointing in RocksDBStateBackend
                 Key: FLINK-6364
                 URL: https://issues.apache.org/jira/browse/FLINK-6364
             Project: Flink
          Issue Type: Sub-task
            Reporter: Xiaogang Shi
            Assignee: Xiaogang Shi


{{RocksDBStateBackend}} is well suited for incremental checkpointing because RocksDB is base on LSM trees,  which record updates in new sst files and all sst files are immutable. By only materializing those new sst files, we can significantly improve the performance of checkpointing.
