Allocate storage groups dynamically, i.e.:
- on table creation allocate only storage groups that are on this
shard;
- allocate a storage group for tablet that is moved to this shard;
- deallocate storage group for tablet that is moved out of this shard.

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.
