---------------------------------
Summary: Provide low level access to RocksDB state backend
Key: FLINK-3947
URL: https://issues.apache.org/jira/browse/FLINK-3947
Project: Flink
Issue Type: Improvement
Components: state backends
Affects Versions: 1.0.3
Reporter: Elias Levy
The current state API is limiting and some implementations are not as efficient
as they could be, particularly when working with large states. For instance, a
ListState is append only. You cannot remove values from the list. And the
RocksDBListState get() implementation reads all list values from RocksDB
instead of returning an Iterable that only reads values as needed.
Furthermore, RocksDB is an ordered KV store, yet there is no ordered map state
API with an ability to iterate over the stored values in order.
