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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
