> Key: CASSANDRA-16604
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16604
> Project: Cassandra
> Issue Type: Task
> Components: Test/unit
> Reporter: Michael Semb Wever
> Assignee: Michael Semb Wever
> Priority: Normal
> Fix For: 2.2.x, 3.0.x, 3.11.x, 4.0.x

> This was raised on the dev ML, where the consensus was to remove it:
> https://lists.apache.org/thread.html/r1ca3c72b90fa6c57c1cb7dcd02a44221dcca991fe7392abd8c29fe95%40%3Cdev.cassandra.apache.org%3E
> The idea is to then replace ant test parallelism with docker container
> parallelism.
> PoC patch:
> https://github.com/apache/cassandra-builds/compare/trunk...thelastpickle:mck/16587-2/trunk
> This is just a quick PoC, aimed at the ci-cassandra agents that have
> 4 cores and 16gb ram available to each executor, but I imagine instead
> something that spawns a number of containers based on system
> resources, like we currently do with get-cores and get-mem.
> Also worth noting the overhead here, compared with the ant parallelism
> approach, docker
> builds everything in each container from scratch, but this too can be
> improved easily enough.
> Cleaning up any remnant `-Dtest.runners=` options is also part of this ticket.
