Browse files Browse the repository at this point in the history 
* make transfer / timer / replication persistence layer accept page token

* get task API on the cassandra side should use page size, not limit

* apply pagination token to timer ack manager

* move duplicated transfer code to one place

* modify test to force pagination

* bugfix: queue ack manager should call processor's complete task fn

* do not keep the lock when doing query
