----------------------------------------------------------------------

patch [here|https://github.com/krummas/cassandra/commits/marcuse/bulkobsolete] - it adds a
bulk obsoletion for truncate
dtests: https://builds.apache.org/view/A-D/view/Cassandra/job/Cassandra-devbranch-dtest/340/
utests: https://circleci.com/gh/krummas/cassandra/120

[~Stefania] do you have time to review this?

edit: my small benchmarks show that this reduces truncate time on a 1600sstable node from
60s to 6s

> Truncate is very slow in 3.0, mostly due to {{LogRecord.make}} listing all files in the
directory for every sstable.
