             Summary: Support more than one retained checkpoints
                 Key: FLINK-23251
                 URL: https://issues.apache.org/jira/browse/FLINK-23251
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / State Backends
            Reporter: Roman Khachatryan
             Fix For: 1.14.0


FLINK-23139 should add private state management capabilities to TM. It does not 
consider multiple retained checkpoints.

>From the offline discussions, there seem to be three options:
 # pass all num-retained snapshots from JM to TM on recovery (and increase 
counts accordingly)
 # do ref count on JM on recovery and send these counts to TM
 # store counts externally (so JM is not involved)

Option 1 seems preferrable.
