[Avi Kivity]

This short report brings to light some interesting commits to scylladb.git master from the last weeks. Commits in the f46b207472..cf47db2bdb range are covered.

Note: scylla.git has been moved to scylladb.git; the full URL is https://github.com/scylladb/scylladb.

There were 181 non-merge commits from 17 authors in that period. Some notable commits:

ScyllaDB version numbers now use semver; this is so that Scylla Operator for Kubernetes can handle release candidates.

There is now a synchronous mode for materialized views. In ordinary, asynchronous materialized views the operation returns before the view is updated. In synchronous materialized view the operation does not return until the view is updated. This enhances consistency but reduces availability as in some situations all nodes might be required to be functional.

Improvements to token calculation mean that large cluster bootstrap is much faster.

The amount of per-table metrics has been reduced by sending metric summaries instead of histograms and not sending unused metrics.

See you in the next issue of last week in scylladb.git master!
