> [HIVE-4617|https://issues.apache.org/jira/browse/HIVE-4617] provides support for async
execution in HS2. There are some proposed improvements in followup JIRAs:
> # [HIVE-5217|https://issues.apache.org/jira/browse/HIVE-5217]
> # [HIVE-5229|https://issues.apache.org/jira/browse/HIVE-5229]
> # [HIVE-5230|https://issues.apache.org/jira/browse/HIVE-5230]
> There is also [HIVE-5060|https://issues.apache.org/jira/browse/HIVE-5060] which assumes
that execute to be asynchronous by default.
>  
> Once they are in, we can think of using the async API as the default for JDBC. This is
likely going to provide performance benefits as a long running query need not keep the underlying
TCP connection open for the entire duration.
