Last week in scylla-cluster-tests.git master (issue #17; 2023-07-28)

This short report brings to light some interesting commits to scylla-cluster-tests.git master from the last week. Commits in the bfd83aa1…da9812ff range are covered.

There were 37 non-merge commits from 12 authors in that period. Some notable commits:

Google Cloud libraries were updated to enable showing labels for addresses. Also a new zone (us-east4) was added to the list of supported zones.

Check out docs on how to clear monitoring docker instances created with hydra investigate show-monitor command.

All tests by default use monitoring from 4.4 branch. Locators adjustment was required to fix screenshot functionality.

Repairing system_auth keyspace after altering replication strategy during node setup was taking much time (especially in multi-dc tests). We speeded it up by running it in parallel on all nodes and adding -pr parameter to repair commands.

New performance test: GCE throughput

Generic test duration was not working in k8s multi-tenant tests. It’s fixed now.

Issue with not timing out ssh command (sshlib2) when there was no output lines was fixed. It enables us to get some more data (like lsof and netstat output) when Scylla freezes during stopping/draining for further issue investigation.

We are deprecating i3 tests. Most of i3 instances were replaced with i4i equivalents (i3en is still in use). No load adjustments were done yet.

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