IIRC it does not delete single-sstable tombstones, but it might... ?

Most likely is what other poster said, that you didn't run cleanup at some
time in the past.

Cassandra Cleanup and disk space

[Luigi Tagliamonte]

Hi Everyone,
I'd like to understand what cleanup does on a running cluster when there is
no cluster topology change, i did a test and i saw the cluster disk space
shrink of 200GB.
I'm using cassandra 2.1.9.

May it be a SizeTieredCompaction of big SSTables just finished and freed
some space?

I did it 2 times and in both times it freed a lot of space, don't think
that it's just a coincidence.

Could it have been that you expanded your cluster a while back, but did not
cleanup then.

Cleanup is specific to a node, may be cleanup was ran one node before and
was ran another node the second time.
