Hi Robert,
By automatic tombstone compaction, I am referring to tombstone_threshold sub
property under compaction strategy in CQL. It is 0.2 by default. So what I
understand from the Datastax documentation is that even if a sstable does not
find sstables of similar size (STCS) , an automatic t

between clusters and is far simpler than sqoop. it "should" even work with
