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.
> A UDF that can export data to JDBC databases.
