Just to let you know that CASSANDRA-17939 has just been committed. It changes the way the CircleCI multiplexer works, in line with the recent changes in our release criteria:
* The default number of repeated tests iterations is 500, except for long and upgrade tests. * It is possible to specify multiple test classes and methods to be repeated into the same config push. So patches altering dozens of tests won't require dozens of config pushes anymore. * Running the .circleci/generate.sh script with -l/-m/-h flags will use git diff to automatically detect the new or modified tests and will add them to the lists of tests to be repeated. The pre-commit workflow will automatically start repeated runs for these tests. The only exception to this are Python dtests, that should be specified manually. * The CircleCI jobs are rearranged so for every regular job there is a companion job to run the repeated tests associated to that job. Those companion jobs will only be visible if there are repeated tests to run. Here <https://app.circleci.com/pipelines/github/adelapena/cassandra/2278/workflows/e339f5d4-0e16-4d4a-bde8-f0d9b9f3912d> is an example run with repeated tests for all the test suites, and here <https://app.circleci.com/pipelines/github/adelapena/cassandra/2269/workflows/d8907cbc-dbca-4d21-bdb9-1a4c58e1a412> is the same workflow without any repeated tests. Some documentation on how to use it can be found here: https://github.com/apache/cassandra/blob/trunk/.circleci/readme.md#running-tests-in-a-loop
