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 94c9cb72a83..2e8e9f874f8 range are covered.

There were 195 non-merge commits from 35 authors in that period. Some notable commits:

  

Alternator, ScyllaDB’s implementation of the DynamoDB API, now keeps HTTP connection [alive](https://github.com/scylladb/scylladb/commit/3b207ea07cae2807ce33740871dece894c832f4f) while shedding requests, avoiding work for connection renegotiation.

The database now configures the operating system to have [no limits](https://github.com/scylladb/scylladb/commit/78c859831972aa8775ffb901e6aeddd881a9f89f) on the number of open file descriptors, to avoid errors due to exhausting the limit when the client opens a very large number of connections. Note other restrictions on connection counts still apply.

The CQL transport now [audits](https://github.com/scylladb/scylladb/commit/5d3580a225dce2f15e1e583c880ae0e7d2d5d1a8) logins using certificates.

The object storage metrics for S3 and GVS were [unified](https://github.com/scylladb/scylladb/commit/e7d41f91780080b5f0c9484d279382b834591657).

Raft can now transfer leadership to a [specific target](https://github.com/scylladb/scylladb/commit/542280ca71f29c1928f5039621a02a56d574fcb9); this is useful for tablet splits.

Full-text search can now generates [highlights](https://github.com/scylladb/scylladb/commit/9bccc77181f5bed1a39bfaebcf11ac351cb50d64) of the document being searched; this is not yet exposed to users.

The SELECT statement’s WHERE clause now [accepts](https://github.com/scylladb/scylladb/commit/1f6690a2fec5e27b476b842c8e4f799e316276b3) IS NOT NULL (previously only allowed only on CREATE MATERIALIZED VIEW) and IS NULL (previously rejected).

In strongly consistent tables, the leader of a tablet will now [step down](https://github.com/scylladb/scylladb/commit/e9b34a4cb954059504409520c7a43146a20ef2f6) during shutdown, minimizing less of availability.

The S3 driver now [backs off](https://github.com/scylladb/scylladb/commit/34825ee4ccff2842e25e4902737641cb8c0c919f) when S3 refuses to serve requests.

The code base is now using [C++26](https://github.com/scylladb/scylladb/commit/fdea2726acc2b8ac8d313d2e45bef8d47a345680).

Support for collectd metrics gathering has been [removed](https://github.com/scylladb/scylladb/commit/a64143513e0a66bafb01529d44af395c82ae05de).

There is a [new configuration framework](https://github.com/scylladb/scylladb/commit/2c5d7d3ee397eec342f2e6732482de3924ea8aca), allowing configuration with overrides at the cluster, datacenter, rack, node, keyspace, and table levels. The configuration is maintained using Raft group 0 and adjusted via ALTER commands.

The SELECT statement can now report the [similarity score](https://github.com/scylladb/scylladb/commit/44e365c553dc6ac3649ad270d4438209a3a96ab8) of a vector search using the ANN() function.

We now [recover](https://github.com/scylladb/scylladb/commit/4e653b90b19082166a34a2d244adff13bf94c4e1) from a failure of an sstable component rewrite.

  

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