-------------------------------------
Summary: User 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
Reporter: Stefan Richter
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.
