- Scylla has a lot in common with Cassandra, from a good reason, like the LSM tree, compaction etc. However, Scylla has a unique CPU&IO schedulers which allows us to prioritize the queries over compaction, and defer compaction to the half milisecond where we have enough idle bandwidth. We have plenty of articles about it
- Scylla has a new (1.5 years) tombstone_gc=repair - a much safer mode
