Maybe I lack context on this, but isn't compaction is schedued in the store fifo queue so there are no concurrent compactions in theory.

Is it a correct understanding?

From backend perspective yes, I meant from client perspective they can schedule multiple requests. They will be put into job queue and executed consecutively.
