Consider the following: 1) table A has N tablets and views 2) migration starts for a tablet of A from node 1 to 2. 3) migration is at write_both_read_old stage 4) coordinator will push writes to both nodes (pending and leaving) 5) A has view, so writes to it will also result in reads (table::push_view_replica_updates()) 6) tablet's update_effective_replication_map() is not refreshing tablet sstable set (for new tablet migrating in) 7) so read on step 5 is not being able to find sstable set for tablet migrating in Causes the following error: "tablets - SSTable set wasn't found for tablet 21 of table mview.users" which means loss of write on pending replica. The fix will refresh the table's sstable set (tablet_sstable_set) and cache's snapshot. It's not a problem to refresh the cache snapshot as long as the logical state of the data hasn't changed, which is true when allocating new tablet replicas. That's also done in the context of compactions for example. Fixes #19052. Fixes #19033. Signed-off-by: Raphael S. Carvalho <raphaelsc@scylladb.com> Closes scylladb/scylladb#19099

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.
