[jira] [Created] (FLINK-10098) Programmatically select timer
storage backend
Elias Levy created FLINK-10098:
----------------------------------
Summary: Programmatically select timer storage backend
Key: FLINK-10098
URL: https://issues.apache.org/jira/browse/FLINK-10098
Project: Flink
Issue Type: Improvement
Components: State Backends, Checkpointing, Streaming, TaskManager
Affects Versions: 1.6.0, 1.7.0
Reporter: Elias Levy
FLINK-9486 introduced timer storage on the RocksDB storage backend. Right now it is only possible to configure RocksDB as the storage for timers by settings the {{state.backend.rocksdb.timer-service.factory}} value in the configuration file for Flink.
As the state storage backend can be programmatically selected by by jobs via {{env.setStateBackend(...)}}, the timer backend should also be configurable programmatically.
Different jobs should be able to store their timers in different storage backends.
