Subject [jira] Commented: (HIVE-645) A UDF that can export data to JDBC databases.
Date Tue, 18 Aug 2009 00:57:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12744312#action_12744312

Raghotham Murthy commented on HIVE-645:
---------------------------------------

In HIVE-758 we made hbase_put a UDAF. It returns the total number of rows loaded. Does it
make sense to have functions that load data into external systems as UDAFs instead of UDFs
with LIMIT 1? The disadvantage is the additional reducer. But, I guess if the information
returned (like total number of rows) is useful, it might be well worth it and not too much
overhead.
