This short report brings to light some interesting commits to scylla-cluster-tests.git master from the last week.
Commits in the 4efd286d…c8c40572 range are covered.
There were 29 non-merge commits from 9 authors in that period. Some notable commits:
A proof-of-concept support for scylla-cloud backend was implemented, enabling SCT to provision clusters in Scylla Cloud without depending on the siren-tests framework. This marks the initial step toward full Scylla Cloud support in SCT.
Support for Z3 small instances was added.
cassandra-stress was upgraded to version 3.18.1, built with Java 21, reinstating the counter_write table creation feature.
Gemini has been upgraded to version 2.1, bringing significant improvements in stability, performance, and usability. A notable addition is a new statement logger, which operates independently of loader disk constraints by utilizing oracle’s disk. In case of data validation errors, all mutations applied to inconsistent partitions (for both test and Oracle clusters) are reported, aiding in detailed issue analysis. Additionally, users can now configure the ratio of inserts, updates, and deletes for greater control.
Gemini is still undergoing a stabilization period. To help uncover potential issues, the gemini_seed parameter is now set to None by default, ensuring some runs use different data distributions and schemas each time.
See you in the next issue of last week in scylla-cluster-tests.git master!
