Hi.
If I have an orc table bucketed and sorted on a column, where does hive
keep the mapping from column value to bucket? Specifically, if I know the
column value, and need to find the specific hdfs file, is there an api to
do this?
Related, is there any documentation on how the read path works f
Dimensions change, and I'd rather do update than recreate a snapshot.

Hello.
Is there a way to write a query with a behaviour equivalent to mysql's "on
duplicate update"? i.e., try to insert, and if key exists, update the row
instead?
thanks,
