Realtime Compute provides a fault tolerance mechanism that allows you to restore data streams so that they are consistent with Realtime Compute. The core of the fault tolerance mechanism is to create consistent snapshots of distributed data streams and their states. These snapshots act as consistency checkpoints to which the system can fall back if a failure occurs.
