This short report brings to light some interesting commits to scylladb.git master from the last week. Commits in the 10c79a4d47…3e22998dc1 range are covered.
There were 28 non-merge commits from 8 authors in that period. Some notable commits:
The CQL NOT IN operator has been implemented. It can be used in the WHERE clause and the IF clause.
Many unit tests are now built into a single executable, reducing build footprint and time.
When selecting replicas for a read, we randomize the replica list order to get better distribution with tablets. The replica list selection itself is faster as well.
The load-and-stream facility has a new scope parameter that can limit data copying to within the same node, the same rack, or the same datacenter. This can improve restore performance when restoring sstables on all racks simultaneously.
See you in the next issue of last week in scylladb.git master!
