Snapshots

A snapshot is a copy of the state of the origin application's data at a specific point in time.

Snapshots are requested via a message sent to the Kafka snapshot request topic and are created by the snapshot agent, which signifies completion by writing a message to the Kafka snapshot response topic.

A snapshot is not a representation of a single data file but rather represents the current state of ALL the origin application's data files, or at least the subset of those files that has been configured for replication.
