Anti-entropy repairs ("nodetool repair") and bootstrap/decom/removenode should stream sections of (and/or possibly entire) sstables from one replica to another. Assuming the original sstable was entirely contained in a single time window, the resulting sstable fragment streamed to the neighbor

Hi Eugene, Common contributors to overlapping SSTables are 1. Hints 2. Repairs 3. New writes with old timestamps (should be rare but technically possible) I would not run repairs with TWCS - as you indicated, it is going to result in overlapping SSTables which impacts disk space and read latency

Hello Michael Schuler, When will this version become available for upgrade from apt-get? I visited the address http://www.apache.org/dist/cassandra/debian and there was no version 3111. To me it is easier to upgrade the nodes this way as I am in a lab, not in a production site. Thanks in
