There are several API endpoints that walk a specific list of sstables and sum up their bytes_on_disk() values. All those endpoints accumulate a map of sstable names to their sizes, then squashe the maps together and, finally, sum up the map values to report it back. Maintaining these intermediate collections is the waste of CPU and memory, the usage values can be summed up instantly. Also add a test for per-cf endpoints to validate the change, and generalize the helper functions while at it. Closes scylladb/scylladb#23143 * github.com:scylladb/scylladb: api: Generalize disk space counting for table and system api: Use map_reduce_cf_raw() overload with table name api: Don't collect sstables map to count disk space usage test: Add unit test for total/live sstable sizes
Scylla in-source tests.

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.
