This short report brings to light some interesting commits to scylla-cluster-tests.git master from the last week. Commits in the db1cced0…f7166ef4 range are covered.
There were 45 non-merge commits from 12 authors in that period. Some notable commits:
SCT gained a structured test documentation system adds a TestMetadata pydantic model to test-case YAML files. It’s going to be injected to Jenkins job as XML (and available for ingestion by Argus and other tools).
On the performance side, a new 2.5TB elasticity latency regression test preps 2.6B rows across 4 loaders and grows the cluster from 3 to 9 nodes (i8g.xlarge) under write/read/mixed workloads. Runs monthly for 2026+ releases.
Tablet-migration waiting changed shape: wait_not_tablet_migration became wait_tablet_balanced, reflecting that the quiesce_topology endpoint now also waits for tablet balancing and no longer needs to be called on every node.
A dead email_data collection path was removed - for some time Argus is handling emails.
On the tooling side, the gemini docker tag moved to v2.6.0, adding single-row UPDATE statements that target real rows, and cql-stress advanced to v0.3.0 with its ScyllaDB driver upgraded to 1.7.0; scylla-bench moved to v1.3.1, a dependency-refresh release built on gocql 1.18.3.
See you in the next issue of last week in scylla-cluster-tests.git master!
