Dawid Wysakowicz commented on FLINK-25872: ------------------------------------------ Do you have an idea for FLINK-23252 already? Do you know when will you perform the unwrapping there? It might influence the choice here. What do you think? Personally, I don't have a preference between the two options suggested in the ticket. I trust your judgement here. IMO, would be good to have a unified story with FLINK-23252. > 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).
