Hi Matthew,
The drillbit sends back two messages to the client:
1) A message with the isLastChunk flag set to true and query state is
PENDING and
2) A terminal messge which has the query state changed to COMPLETED
(isLastChunk may be false).
I believe the JDBC driver batches these two messages so they are delivered
together (see QueryResultHandler.java:batchArrived()
Not sure what you're trying to achieve., but HTH.
