--------------------------------------

             Summary: Heartbeat Fails when C++ client receives a large ResultSet
                 Key: DRILL-5217
                 URL: https://issues.apache.org/jira/browse/DRILL-5217
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - C++
            Reporter: Sudheesh Katkam
            Priority: Critical


If the listener thread is occupied for longer than 15 seconds (heartbeat timeout) while [handling a message from the drillbit|https://github.com/apache/drill/blob/master/contrib/native/client/src/clientlib/drillClientImpl.cpp#L1286] e.g. [processing query data blocks if the query result listener's buffer is full|https://github.com/apache/drill/blob/master/contrib/native/client/src/clientlib/drillClientImpl.cpp#L899], heartbeats fail because the same thread is responsible for sending heartbeats!

Fix is to [handle long running operations|http://stackoverflow.com/questions/17648725/long-running-blocking-operations-in-boost-asio-handlers] separately using boost asio.
