Subject [jira] [Commented] (PHOENIX-3860) Implement TAL functionality for Omid
Date Wed, 31 May 2017 21:20:04 GMT


James Taylor commented on PHOENIX-3860:

I'm not sure that's feasible. To be reliable, you'd need to read all cells across all column
families in a row in order to issue a delete against every column qualifier. You'd have a
race condition then too against an upsert (i.e. Put) coming in on that row while the delete
is happening. You could sometimes know in advance what possible column qualifiers a row would
have, but unfortunately not always.

Maybe you could borrow the Tephra filter that enforces column and family deletes through their
own tombstone markers?
