----------------------------------
Summary: There is no API to configure the timer state backend
Key: FLINK-10372
URL: https://issues.apache.org/jira/browse/FLINK-10372
Project: Flink
Issue Type: Improvement
Components: DataStream API, State Backends, Checkpointing
Affects Versions: 1.6.0
Reporter: Elias Levy
Flink 1.6.0, via FLINK-9485, introduced the option to store timers in RocksDB
instead of the heap. Alas, this can only be configured via the
{{state.backend.rocksdb.timer-service.factory}} config file option. That means
that the choice of state backend to use for timer can't be made on a per job
basis on a shared cluster.
There is a need for an API in {{RocksDBStateBackend}} to configure the backend
per job.
