This short report brings to light some interesting commits to scylla-cluster-tests.git master from the last week.
Commits in the a6571cc3…1936d3c4 range are covered.
There were 12 non-merge commits from 5 authors in that period. Some notable commits:
Due to reaching the AWS Security Groups limit, the cloud cleanup process will now periodically remove any unused security groups that aren’t tagged with keep:alive.
We’ve refactored how nodes are selected and assigned to nemeses, introducing the new NemesisNodeAllocator entity, which centralizes node selection and tracking to avoid the complexity and race conditions from locking in multiple places.
To minimize capacity issues and prevent tests from impacting each other, we’ve enabled Jenkins throttle-concurrents plugin for performance tests, so only one test will run at a time in the same region.
Finally, rsync will now be installed by default since it better fits our synchronization needs and is generally preferred for file transfers.
See you in the next issue of last week in scylla-cluster-tests.git master!
