Yun Tang resolved FLINK-23252. ------------------------------ Resolution: Fixed merged in master: 7b48eae6b448963e0aed2b33d06e105311a48e05 and ece745c39eaee7caaa1a9d077f079543cb088f67 > Support recovery (from checkpoints) after disabling changelog backend > --------------------------------------------------------------------- > > Key: FLINK-23252 > URL: https://issues.apache.org/jira/browse/FLINK-23252 > Project: Flink > Issue Type: Sub-task > Components: Runtime / State Backends > Reporter: Roman Khachatryan > Assignee: Hangxiang Yu > Priority: Major > Labels: pull-request-available > Fix For: 1.16.0 > > > Recovery from savepoint already works: > * changelog off -> on: FLINK-23278 > * changelog on -> off: directly calling > {{{}underlyingBackend.{}}}{{{}savepoint{}}}{{{}(){}}} (instead of > {{{}writer.persist(){}}}) > > For checkpoints, changelog on -> off doesn't work. Regular state backend will > receive materialized and non-aterialized state on recovery. To support it, > state changes have to be applied on recovery even if changelog backend is > disabled. > Another obstacle could be that wrapped backend state handles created during > materialization can refer to a fake checkpoint ID. This fake checkpoint ID > would then be passed to e.g. RocksIncrementalSnapshotStrategy on restore. -- This message was sent by Atlassian Jira (v8.20.7#820007)
