When a tablet is migrated away, any inactive read which might be reading from said tablet, has to be dropped. Otherwise these inactive reads can prevent sstables from being removed and these sstables can potentially survive until the tablet is migrated back and resurrect data. This series introduces the fix as well as a reproducer test. Fixes: https://github.com/scylladb/scylladb/issues/18110 Closes scylladb/scylladb#18179 * github.com:scylladb/scylladb: test: add test for cleaning up cached querier on tablet migration querier: allow injecting cache entry ttl by error injector replica/table: cleanup_tablet(): clear inactive reads for the tablet replica/database: introduce clear_inactive_reads_for_tablet() replica/database: introduce foreach_reader_concurrency_semaphore reader_concurrency_semaphore: add range param to evict_inactive_reads_for_table() reader_concurrency_semaphore: allow storing a range with the inactive reader reader_concurrency_semaphore: avoid detach() in inactive_read_handle::abandon()

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.
