Package io.debezium.connector.mongodb

Class ReplicaSetOffsetContext

java.lang.Object

io.debezium.connector.mongodb.ReplicaSetOffsetContext

All Implemented Interfaces:

OffsetContext

@ThreadSafe
public class ReplicaSetOffsetContext
extends Object
implements OffsetContext

An OffsetContext implementation that is specific to a single ReplicaSet. The mongodb connector operates multiple threads during snapshot and streaming modes where each ReplicaSet is processed individually and the offsets that pertain to that ReplicaSet should be maintained in such a way that is considered thread-safe. This implementation offers such safety.
