You are right, you could set concurrent_compactors to 1 to just allow a single
compaction at a time. However, that isn't feasible in our scenario with
multiple data dirs as compactions would accumulate.
We wan't to run multiple compactions in parallel but only one per data dir...
Best,

There's a concurrent_compactors parameter in cassandra.yml that does
exactly what the name says. You may also find
compaction_throughput_mb_per_sec useful.

Hi there,
we recently upgraded from 2.2 to 3.11.4.
Unfortunately, we are running into problems with the compaction scheduling,
now. From time to time, a bunch of compactions (e.g. 6) are scheduled for the
same data dir. This makes no sense for spinning disks as it will slow down all
compaction
