Subject [jira] [Updated] (HIVE-12428) Provide an option for HiveServer2 to stream serialized thrift results when they are available
Date Mon, 16 Nov 2015 23:43:11 GMT

     [ https://issues.apache.org/jira/browse/HIVE-12428?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vaibhav Gumashta updated HIVE-12428:
------------------------------------
    Description: Once HIVE-12049 is complete, we will have an option on HS2 side to avoid
paying the deserialization penalty and simple stream batches of rows on the wire which the
*DBC driver can appropriately interpret. This can be done by changing the FetchOperator such
that when it has the thrift formatted row sets available, it uses the fastpath. For queries
where tasks don't write thrift rowsets, the current implementation will suffice.
