[jira] [Updated] (PIG-3013) BinInterSedes improve chararray sort performance

["Rohini Palaniswamy (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-3013?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rohini Palaniswamy updated PIG-3013:
------------------------------------

    Attachment: PIG-3013.patch

Ran the full suite of unit tests and they passed (no new errors than the pending ones in PIg-2972). Did not add a new unit test as TestOrderBy3.testValuesASC and testValuesDESC already test the ordering for chararray and exercise this codepath.

[~jcoveney],
   Do you want to include this in 0.11 as well?

> In PIG-2975, Koji found that there is a extra array copy during byte array comparison and fixing that gave a 15-20% performance improvement. Same is the case with chararray.
