This short report brings to light some interesting commits to [scylla-cluster-tests.git master](https://github.com/scylladb/scylla-cluster-tests) from the last week. Commits in the ff781b5a…5fbbee4c range are covered.

There were 67 non-merge commits from 16 authors in that period. Some notable commits:

The constraint-based sizing rollout reached most of the test-case tree. Hardcoded `instance_type_*` parameters were replaced with `sizing_db`/`sizing_loader`/`sizing_monitor` constraint blocks across the [longevity configs](https://github.com/scylladb/scylla-cluster-tests/commit/881870161693fc160daf8bf137125df2b5bb41ee),[alternator cases](https://github.com/scylladb/scylla-cluster-tests/commit/39431a66fd0d51b15df60ba9e0d3370d674dac83).

The OCI backend gained [IPv6 networking and secondary VNIC attachment](https://github.com/scylladb/scylla-cluster-tests/commit/63a5510dd321752336040dec070d7f41b0fa495b). CI jobs reusing the [multi-VNIC configuration](https://github.com/scylladb/scylla-cluster-tests/commit/5cbe8071a73007a4eb583e9d8a2a66d64582eeb5) came with it.

Gemini’s oracle cluster now [works on GCE and Azure](https://github.com/scylladb/scylla-cluster-tests/commit/d961e11a72ce2e24a0f678da9acf36a403d9340e), not just AWS and OCI.

Monitoring [moved to the 4.16.x branch](https://github.com/scylladb/scylla-cluster-tests/commit/d455a6fbbc0f780e032ebba1ac0a487698ba8880).

Weekly microbenchmarks gained [read and write jobs for the `perf-cql-raw` tool](https://github.com/scylladb/scylla-cluster-tests/commit/bd7402ce460b4c7ef078e5bec349bba2ae993777) on x86\_64 and arm64, next to the existing `perf-simple-query` ones. The same jobs are also [triggered by the PGO offline installer pipeline](https://github.com/scylladb/scylla-cluster-tests/commit/b319ba8f88867d6f273c09fd86d8ba2dbc5ec0e1).

Two experimental [logstor performance pipelines driven by latte](https://github.com/scylladb/scylla-cluster-tests/commit/5fbbee4c66bc717f6754b9f6d0fff547c2ba0a85) landed, with uniform and hotspot workloads at 600k and 750k op/s.

The latte image itself [moved to 0.51.0](https://github.com/scylladb/scylla-cluster-tests/commit/51d7638e4c2f085788ac0822614a7b58e15ac441), which picks up the Rust `scylla` driver 1.8.0, replaces `SimpleStrategy` with `NetworkTopologyStrategy` in its schema, and fixes a retry backoff overflow past attempt 64.

ScyllaDB is dropping the scylla-housekeeping subsystem, so [all housekeeping checks and code were removed from SCT](https://github.com/scylladb/scylla-cluster-tests/commit/ea08369d66780a6a8428a0cecca018cef6e1b0e2).

See you in the next issue of last week in scylla-cluster-tests.git master!
