RocksDBKeyedStateBackend<K>
An
AbstractKeyedStateBackend that stores its state in RocksDB and serializes
state to streams provided by a CheckpointStreamFactory
upon checkpointing. |

interface |
CheckpointableKeyedStateBackend<K>
Interface that combines both, the
KeyedStateBackend interface, which encapsulates methods
responsible for keyed state management and the SnapshotStrategy which tells the system
how to snapshot the underlying state. |
