Subject [jira] [Commented] (PHOENIX-1875) implement ARRAY_PREPEND built in function
Date Thu, 07 May 2015 15:14:00 GMT

James Taylor commented on PHOENIX-1875:
---------------------------------------

No, we don't want to store trailing null values, so I wouldn't append anything in this case.

See PHOENIX-777 - that'd be great if you could work on that next, [~Dumindux]. Take care to
maintain backward compatibility in our array serialization format.
