Examples of edu.brown.hstore.callbacks.SendDataCallback

edu.brown.hstore.callbacks.SendDataCallback
This callback waits until all of the TransactionMapResponses have come back from all other partitions in the cluster. The unblockCallback will switch the MapReduceTransaction handle into the REDUCE phase and then requeue it at the local HStoreSite @author pavlo
