Eric Hanson created HIVE-4961:
---------------------------------
Summary: Create bridge for custom UDFs to operate in vectorized
mode
Key: HIVE-4961
URL: https://issues.apache.org/jira/browse/HIVE-4961
Project: Hive
Issue Type: Sub-task
Reporter: Eric Hanson
Assignee: Eric Hanson
Suppose you have a custom UDF myUDF() that you've created to extend hive. The
goal of this JIRA is to create a facility where if you run a query that uses
myUDF() in an expression, the query will run in vectorized mode.
This would be a general-purpose bridge for custom UDFs that users add to Hive.
It would work with existing UDFs.
I'm considering a separate JIRA for a new kind of custom UDF implementation
that is vectorized from the beginning, to optimize performance. That is not
covered by this JIRA.
