> Configurable RocksDBStateBackend options factory

> Key: FLINK-10912
> URL: https://issues.apache.org/jira/browse/FLINK-10912
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Affects Versions: 1.7.0
> Reporter: Thomas Weise
> Assignee: Yun Tang
> Priority: Major
>
> RocksDB has a ton of configuration options and users should be able to reach
> those, when necessary. Currently there are a few predefined configurations
> that can be activated programmatically [1] [2]. This requires change to the
> pipeline construction code that's hard or impossible when using higher level
> API or frameworks such as Apache Beam. It would be good to support an options
> factory that can be specified as part of the state backend configuration in
> flink-conf.yaml.
