Aljoscha Krettek commented on FLINK-3417:
-----------------------------------------
On second thought. I don't think this is possible if the RocksDB state backend
is not part of flink-dist because then RocksDB is only available if the user
includes it in their user jar.
So, two options:
- Don't have a state factory for RocksDB and don't allow configuring it in the
flink conf
- Make RocksDB part of dist, add RocksDB dependency to dist
> Add RocksDB StateBackendFactory and integrate with Flink Config

> URL: https://issues.apache.org/jira/browse/FLINK-3417
> Project: Flink
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 1.0.0
> Reporter: Aljoscha Krettek
> Priority: Blocker
>
> Currently, only memory and file backends can be configured as default
> backends in {{flink-conf.yaml}}. To change that we need to add a
> StateBackendFactory.
> Also, there cannot be a short name for this such as how you can now specify
> "jobmanager" or "filesystem" in the config because RocksDB is not in the
> standard dist.
