Subject [jira] [Commented] (HIVE-2470) Improve support for Constant Object Inspectors
Date Fri, 30 Sep 2011 18:59:45 GMT


Jonathan Chang commented on HIVE-2470:

If we go with the second, I can add the functionality to GenericUDF directly but this will
involve either changing all the call sites of GenericUDF or all the UDFs both of which seem
pretty risky.

> ConstantObjectInspectors are nice but they need to be more widely supported and used.
 In particular,
> * More functions need to be using them.
> * There need to be facilities for propagating constness.
> * Support for complex types must be added.
