Class ShardSyncTaskManager

java.lang.Object

software.amazon.kinesis.leases.ShardSyncTaskManager

public class ShardSyncTaskManager
extends Object

The ShardSyncTaskManager is used to track the task to sync shards with leases (create leases for new Kinesis shards, remove obsolete leases). We'll have at most one outstanding sync task at any time. Worker will use this class to kick off a sync task when it finds shards which have been completely processed.
