This short report brings to light some interesting commits to scylla-cluster-tests.git master from the last week. Commits in the 29744f38…baa8624a range are covered.
There were 15 non-merge commits from 5 authors in that period. Some notable commits:
Latte tool was upgraded to 0.28.2-scylladb, introducing real-time streaming of HDR histogram data and improving latency calculations by addressing coordinated omission. It can now run similarly to cassandra-stress by mimicking its schema and queries.
cassandra-stress, cql-stress, and latte metrics are now combined in monitoring panels based on metric types.
Scylla Manager testing saw several improvements, including a more flexible snapshot preparation process, additional parameterization, support for cloud clusters, and sending snapshot details to Argus Results for easier access.
To prepare for broader HDR histogram support in benchmarking tools, the use_hdr_cs_histogram SCT config option was renamed to use_hdrhistogram, removing the cassandra-stress reference. Related modules were also renamed and moved to a common location.
is_enterprise node property was fixed for 2025.1, resolving several issues with enterprise feature testing in source-available Scylla.
See you in the next issue of last week in scylla-cluster-tests.git master!
