What is StateSnapshotting in Storm?

In Storm, StateSnapshotting is a mechanism used to save and restore state. When a StateSnapshotting object is created, Storm periodically saves the current state snapshot to a persistent storage for later recovery if needed. This mechanism ensures continuity and consistency of state in stateful topologies, even in the event of failure or restart. Utilizing StateSnapshotting enables a more reliable and robust streaming processing system.
