We have new tombstone reaping functionality in the works for Riak KV 2.3,
which should allow for safe and automatic removal of old leftover
tombstones. In the mean time, you can potentially trigger the deletion of
old, leftover tombstones by doing reads to those keys; if all the primary
replicas return the tombstone then Riak will automatically try and remove
Note, however, that this will not immediately reclaim disk space. Deletion
of the tombstone by Riak will still leave behind a backend tombstone for
some amount of time. See the docs here for more info on this:
As for estimating disk space used by tombstones, I'm afraid I don't know of
any easy way to do that. Hopefully someone else may have a good suggestion
