-----------------------------------
Summary: Use ResourceGuard to make sure snapshot quit before ForSt
dispose
Key: FLINK-37597
URL: https://issues.apache.org/jira/browse/FLINK-37597
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Affects Versions: 2.0.0
Reporter: Zakelly Lan
Assignee: Zakelly Lan
Fix For: 2.1.0
Currently, there might be a chance that the forst state backend dispose when
on-going snapshots are still in progress. This would be problematic since the
db will coredump when enabling file deletion while the db core is already
closed. This happens when the snapshot finishes after forst state backend
disposes. We should apply ResourceGuard to protect the disposal order of db and
snapshot, like RocksDB does.
