Roman Khachatryan updated FLINK-25872:
--------------------------------------
Description: 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). This bug is like FLINK-25478. (was: If we restore from incremental
checkpoint with changelog state-backend enabled in snapshot CLAIM mode, the
restored checkpoint would be discarded on subsume, which lead to the private
state in Incremental state handle could be deleted by mistake. This bug is like
FLINK-25478.)
Environment: The issue also affects non-incremental checkpoints, updating
the ticket.
Summary: Restoring from non-changelog checkpoint with changelog
state-backend enabled in CLAIM mode discards state in use (was: Restoring from
incremental non-changelog checkpoint with changelog state-backend enabled in
CLAIM mode discards state in use)
