Drop old mobile apps tables
Closed, ResolvedPublic

Description

In T153133 we've switched mobile apps to key_rev_value bucket in order to support access by revision. After the new tables fill up a little we need to completely switch to them and delete old tables and update the RESTBase code not to use them.

Event Timeline

RESTBase was switched to using new tables, so old tables could be dropped from Cassandra now. Let's wait a bit to make sure all's fine before actually dropping the tables.

@Eevans do you need more time to investigate the latencies on these table? Don't think so, but just double-checking.

AFAIK we're good to go.

Cool. I will do that early next week. Wanna have some buffer time in case we'd need to rollback the switch

It took some time, but I've finally dropped all the old key spaces. Resolving.
