------------------------------------
Summary: 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
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.
