Roman Khachatryan commented on FLINK-25872: ------------------------------------------- Yes, there is a PR already for FLINK-23252. But the problem there is different: state changes need to be applied (on TMs) and SharedStateRegsitry (on JM) is not affected. So I think they are not related. > Restoring from non-changelog checkpoint with changelog state-backend enabled > in CLAIM mode discards state in use > ---------------------------------------------------------------------------------------------------------------- > > Key: FLINK-25872 > URL: https://issues.apache.org/jira/browse/FLINK-25872 > Project: Flink > Issue Type: Bug > Components: Runtime / Checkpointing, Runtime / State Backends > Reporter: Yun Tang > Assignee: Yanfei Lei > Priority: Major > Labels: pull-request-available > Fix For: 1.16.0 > > > If we restore from checkpoint with changelog state-backend enabled in > snapshot CLAIM mode, the restored checkpoint would be discarded on subsume. > This invalidates newer/active checkpoints because their materialized part is > discarded (for incremental wrapped checkpoints, their private state is > discarded).
