Subject [jira] [Updated] (HIVE-14452) Vectorization: BinarySortableDeserializeRead should delegate buffer copies to VectorDeserializeRow
Date Sat, 06 Aug 2016 01:14:20 GMT

     [ https://issues.apache.org/jira/browse/HIVE-14452?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gopal V updated HIVE-14452:
---------------------------
    Description: 
Since the VectorDeserializeRow already calls a setVal(), the copy inside the lower layer is
entirely wasteful.

{code}
BinarySortableSerDe.deserializeText(
              inputByteBuffer, columnSortOrderIsDesc[fieldIndex], tempText);
{code}

With HIVE-14451, the copies can be avoided for some scenarios and retained for others.
