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 ebc100f74f…5eadea301e range are covered.

There were 38 non-merge commits from 12 authors in that period. Some notable commits:

  

The row cache will now [purge expired tombstones](https://github.com/scylladb/scylladb/commit/ce96b472d39a6c72f99176c8cf84e171143ae046) before populating the cache, removing the performance impact of scanning tombstones. Note that non-expired tombstones are still loaded.

Consistent schema management using Raft is now [enabled by default](https://github.com/scylladb/scylladb/commit/5c886e59de1515210a04f0c6f12f398b9e6dd19d) for new clusters. Upgraded clusters default to raft disabled for schema management.

Alternator, ScyllaDB’s implementation of the DynamoDB API, improved its performance by compiling regular expressions used to validate information [during process startup](https://github.com/scylladb/scylladb/commit/b28818db06a97cbc942fe0f82b8a15f13bd853ac).

The compaction manager reloads sstables during schema change, but it did so with quadratic complexity, causing stalls for tables that had many sstables. This is now [fixed](https://github.com/scylladb/scylladb/commit/87ee54712071c3eacb03b0463e5db7187742ff1e).

  

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