Vaibhav Gumashta updated HIVE-5232:
-----------------------------------
Description:
[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]
# [HIVE-5441|https://issues.apache.org/jira/browse/HIVE-5441]
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 can enable the server to report back error sooner to the client. It can
also be useful in cases where a statement.cancel in a different thread and the
original thread will now be able to detect that.

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.
