The facility that data store nodes use to send updates to the data server. The implementation uses a {@link RequestQueueClient} to communicate requeststo the server in order. It makes sure that transactions are committed in order, and that locks are not released until the transactions in which they were used have committed. It limits the number of unacknowledged commit requests that can appear in the queue to make sure that the node does not outstrip the capacity of the server. Eviction and downgrade requests are not limited in the queue, though, since they represent a response to requests already being processed on the server.
This class is part of the implementation of {@link CachingDataStore}.
