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 6eca7e4ff6b..3dea15bc9d3 range are covered.

There were 161 non-merge commits from 30 authors in that period. Some notable commits:

  

A basic (very limited and very experimental) implementation of [strongly consistent tables](https://github.com/scylladb/scylladb/commit/4e984139b2768e2f6010eb4d0e6796da90e6b4d7) using Raft has been merged.

Node decommissions can now be [executed in parallel](https://github.com/scylladb/scylladb/commit/67045b5f17d9c0381952025d4367ed29a216a6f2) with each other and with bootstraps. Previously decommissions were executed serially and could not run in parallel with bootstraps.

You can now [filter](https://github.com/scylladb/scylladb/commit/34d28475d908dd79f0974bf37a0d17b1ff21b532) vector searches using the WHERE clause.

The filters for vector searches are now [prepared beforehand](https://github.com/scylladb/scylladb/commit/5c1e525618d4eeb48748638adf1405c9db57085f) for prepared statements to reduce per-query overhead.

Vector indexes now support [quantization and oversampling](https://github.com/scylladb/scylladb/commit/70b3cd0540f173b8c6cc63d4cf0db7dbbc52b717), leading to reduced memory usage and improved accuracy respectively.

Vector indexes now support the [rescoring](https://github.com/scylladb/scylladb/commit/8962093d903eb07abf27c8d826a524966d261d1b) option, which [improves search quality](https://github.com/scylladb/scylladb/commit/3ec4f67407aa6607d5f36c06e616f75ec2c113b1), especially in conjunction with quantization.

The log-structured allocator, used for memtables and cache, now reports more detailed [metrics](https://github.com/scylladb/scylladb/commit/dd0fc35c63501303551e20a723830af7c7ad7f8d) when memory reclaim stalls.

The system.load\_per\_node virtual table now [reports](https://github.com/scylladb/scylladb/commit/7977c97694af6a19708c53f4c2cae9d2a950bb04) the total node storage capacity.

Compatibility for system tables layout that predates ScyllaDB 2.0 was [removed](https://github.com/scylladb/scylladb/commit/36347c3ce957c51138f2559cf85e0531cb58b46c).

Automatic migration from pre-Raft authentication system tables now uses [paging](https://github.com/scylladb/scylladb/commit/09d3b6c98b7ca127d88379aa8bfa9f839a8d7f5d) to avoid memory overload.

Repair-based node operations (adding and removing nodes, with vnodes) are now correctly [fenced](https://github.com/scylladb/scylladb/commit/cf4133c62dc4374e89e92a164e83f525a2609b6e) if an incompatible topology operation is performed.

User-defined service levels are now [grouped](https://github.com/scylladb/scylladb/commit/18b5a49b0c0e3601b6881a64aebaad82754f7ea2) into a single scheduling group; this prevents scheduling edge-cases where background activity dominates over the user workload.

The default sstable compression options now also [apply](https://github.com/scylladb/scylladb/commit/4281d18c2e4646511035af80705fa1c27072e668) to alternator tables.

There is now configuration to force [automatic expansion](https://github.com/scylladb/scylladb/commit/7d2e6c017011dd715e4cba2c983b63ccc97a98b3) of replication factors to rack lists.

Snapshot manifests, used for backup, are now [extended with tablet information](https://github.com/scylladb/scylladb/commit/cb6ee05391f158ce9e7299d365f617e44f9839ea) allowing for fast restore, including to clusters with different topology.

The master branch version was [updated](https://github.com/scylladb/scylladb/commit/3dea15bc9d3951d5befc0ac4156788a9dd52bd75) to 2026.2.0-dev, indicating the start of the 2026.1 stabilization cycle and the 2026.2 development cycle.

  

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