This short series fixes a regression from Scylla 5.2 to Scylla 5.4 in "SELECT * GROUP BY" - this query was supposed to return just a single row from each partition (the first one in clustering order), but after the expression rewrite started to wrongly return all rows. The series also includes a regression test that verifies that this query works doesn't work correctly before this series, but works with this patch - and also works as expected in Scylla 5.2 and in Cassadra. Fixes #16531. Closes scylladb/scylladb#16559 * github.com:scylladb/scylladb: test/cql-pytest: check that most aggregators don't take "*" cql-pytest: add reproducer for GROUP BY regression cql: fix regression in SELECT * GROUP BY

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.
