Looks good. I think we could even go one step further and have a shortcut
(`rocksdb`) similar to `filesystem` and `jobmanager`.
We should then also have dedicated options, like
`state.backend.rocksdb.checkpointdir`.
> Add StateBackendFactory for RocksDB Backend
> -------------------------------------------
>
> Key: FLINK-4579
> URL: https://issues.apache.org/jira/browse/FLINK-4579
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Reporter: Aljoscha Krettek
> Assignee: Jark Wu
>
> Right now, we only have a {{StateBackendFactory}} for the {{FsStateBackend}}
> which means that users cannot specify to use the RocksDB backend in the flink
> configuration.
> If we add a factory for rocksdb we should also think about adding the rocksdb
> backend to the standard distribution lib, otherwise it is only usable if
> users manually place the rocks jars in the Flink lib folder.
