Actually sumo_store_riak:delete_by/2 is returning the number of deleted docs: https://github.com/inaka/sumo_db/blob/master/src/sumo_store_riak.erl#L129.

So, @elbrujohalcon should we close this issue?

If there's a test and it is evaluated for the riak store (among others) and it passes, then yes, @cabol

[cabol]

Yes we're testing it, E.g.: https://github.com/inaka/sumo_db/blob/master/test/sumo_basic_SUITE.erl#L132

PD: In fact, thanks to this test we discovered an issue with sumo_store_mongo:delete_by/2, which is not returning the total of deleted docs (issue #225). BTW, it was fixed already.

Ok
