under most circumstances, we don't care the ordering of the sstable identifiers, as they are just identifiers. so, as long as they can be compared, we are good. but we have tests with expect that the sstables can be ordered by the time they are created. for instance, sstable_run_based_compaction_test has this expectaion. before this change, we compare two UUID-based generations by its (MSB, LSB) lexicographically. but UUID v1 put the lower bits of the timestamp at the higher bits of MSB, so the ordering of the "time" in timeuuid is not preserved when comparing the UUID-based generations. this breaks the test of sstable_run_based_compaction_test, which feeds the sstables to be compacted in a set, and the set is ordered with the generation of the sstables. after this change, we consider the UUID-based generation as a timeuuid when comparing them.

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.
