Hi @adejanovski, just wondering, what is the reason we want to make sure that we do not have 2 repair sessions of different types running at the same time? Is it just to avoid overstreaming?

Hi @kzalys, having multiple threads working concurrently on the same sstables is a good way to shoot yourself in the foot and opens the door to race conditions in Cassandra itself. An sstable cannot be compacted and anticompacted at the same time, which is one type of conflict that can happen.
The overstreaming and additional pressure put on the cluster is another good reason not to do this indeed.
