Yun Tang closed FLINK-5730.
---------------------------
Resolution: Invalid
Current RocksDB snapshots would copy the kv state information in the sync phase
to avoid this problem. Closing this ticket.
> Users can concurrently modify state metadata of RocksDB asynchronous snapshots

> Key: FLINK-5730
> URL: https://issues.apache.org/jira/browse/FLINK-5730
> Project: Flink
> Issue Type: Bug
> Components: Runtime / State Backends
> Reporter: Stefan Richter
> Priority: Minor
> Labels: auto-deprioritized-major
>
> The current implementation of asynchronous snapshots in RocksDB iterates the
> original state metadata structures as part of the asynchronous snapshot.
> Users could potentially modify the state metadata concurrently (e.g. by
> registering a new state while the snapshot is running), thereby corrupting
> the metadata.
> For the way most users are registering their states (at the start of the
> task), this is not a problem. However, if state is conditionally registered
> at some later point in time this can be problematic.
