Last week in scylla-cluster-tests.git master (issue #105; 2025-08-15)

This short report brings to light some interesting commits to scylla-cluster-tests.git master from the last week. Commits in the bdab118b…959e222a range are covered.

There were 27 non-merge commits from 8 authors in that period. Some notable commits:

Added fallback to Azure SDK reboot when walinuxagent is absent ensuring Azure VMs based on non-official images can still be restarted reliably.

Switched artifact I/O tuning to use scylla_io_setup instead of direct iotune to align with current Scylla logic and improve result correctness.

Preserved original spacing in events sent to Argus fixing unintended trimming in some cases.

Added rack-aware support for the Python driver tests.

A new Rust performance test using cql-stress was added.

New performance tests branch branch-perf-v17 was created. Key workloads migrated include rolling upgrade vnodes, elasticity, and microbenchmark jobs.

Introduced vector-store service deployment for the Docker backend enabling VS testing in containerized environments.

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