Last week in scylla-cluster-tests.git master (issue #47; 2024-05-17)

This short report brings to light some interesting commits to scylla-cluster-tests.git master from the last week.
Commits in the d3021bbd…819ad1e7 range are covered.

There were 15 non-merge commits from 5 authors in that period. Some notable commits:

To speed up test setup, we now configure and start the DB cluster, loaders, monitors, and Oracle cluster in parallel. This change has reduced setup time by approximately 20 minutes for a 6-node DB cluster.

We added a bisect decorator that allows bisection functionality for selected SCT tests. This feature is still experimental, as it has only been tested in one performance scenario, and requires some preparation of tests to work fully. More details can be found in the documentation. It is limited to published binaries in ScyllaDB downloads.

Since cassandra-stress is not included in the latest Scylla Docker images, loaders will use version 5.4.6.

To further speed up SCT test setup, monitors and loaders will no longer configure memory swap space.

Running a multi-DC cluster test from a local machine has been fixed.

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