The non-streaming loading of sstables performs cleanup since recently [1]. For vnodes, unfortunately, cleanup is almost unavoidable, because of the nature of vnodes sharding, even if sstable is already clean. This leads to waste of IO and CPU for nothing. Skipping the cleanup in a smart way is possible, but requires too many changes in the code and in the on-disk data. However, the effort will not help existing SSTables and it's going to be obsoleted by tablets some time soon. Said that, the easiest way to skip cleanup is the explicit --skip-cleanup option for nodetool and respective skip_cleanup parameter for API handler. New feature, no backport fixes #24136 refs #12422 [1] Closes scylladb/scylladb#24139 * github.com:scylladb/scylladb: nodetool: Add refresh --skip-cleanup option api: Introduce skip_cleanup query parameter distributed_loader: Don't create owned ranges if skip-cleanup is true code: Push bool skip_cleanup flag around

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
