----------------------------------
Summary: QueryableState: requesting a non-existing key in
RocksDBStateBackend is not consistent with the MemoryStateBackend and
FsStateBackend
Key: FLINK-5613
URL: https://issues.apache.org/jira/browse/FLINK-5613
Project: Flink
Issue Type: Bug
Components: Queryable State
Affects Versions: 1.2.0
Reporter: Nico Kruber
Assignee: Nico Kruber
Querying for a non-existing key for a state that has a default value set
currently results in the default value being returned in the
RocksDBStateBackend only. MemoryStateBackend or FsStateBackend will return null
which results in an UnknownKeyOrNamespace exception.
Default values are now deprecated and will be removed eventually so we should
not introduce them into the new queryable state API and thus adapt the
RocksDBStateBackend accordingly
