             Summary:  Introducing `parallel recovery` mode for fully checkpoint (savepoint)
                 Key: FLINK-8845
                 URL: https://issues.apache.org/jira/browse/FLINK-8845
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
    Affects Versions: 1.5.0
            Reporter: Sihua Zhou
            Assignee: Sihua Zhou
             Fix For: 1.6.0


Base on {{ingestExternalFile()}} and {{SstFileWriter}} provided by RocksDB, we can restore from fully checkpoint (savepoint) in parallel. This can also be extended to incremental checkpoint easily, but for the sake of simple, we do this in two separate tasks.
