This short report brings to light some interesting commits to [scylladb.git master](https://github.com/scylladb/scylladb/) from the last week. Commits in the e18a855abe…afee3924b3 range are covered.

There were 69 non-merge commits from 15 authors in that period. Some notable commits:

  

When tablet metadata (system.tablets table) changes, we now [reload only the changed rows](https://github.com/scylladb/scylladb/commit/318278ff928a7ef95365647fbb91fd1c2e8f0f5b).

A bug when ALTERing a keyspace that doesn’t exist, with tablets, was [fixed](https://github.com/scylladb/scylladb/commit/a3d53bd22476b3fbf552b1feb3bae79c21749acb).

Reversed queries (`WITH CLUSTERING ORDER BY`) are already quite efficient in ScyllaDB, yet the wire protocol between nodes was kept unaware of reversed queries in order to maintain compatibility; result sets were un-reversed before sending over the wire, then re-reversed. We now support an alternate protocol where these wasteful transformations are [avoided](https://github.com/scylladb/scylladb/commit/8c257db28322a134e131ae2200200c6f878a5c8a).

A regression in processing limits for the GROUP BY clause was [fixed](https://github.com/scylladb/scylladb/commit/3de4e8f91b338151142a6915e0c195e410df7681).

Service levels are used to group and classify sessions. Service level names beginning with `$` are now [reserved](https://github.com/scylladb/scylladb/commit/f7eb74e31f322f2d44e0a4d1b6f9a4b19df65c0d).

  

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