Roman Puchkovskiy updated IGNITE-25445:
---------------------------------------
Description:
PartitionMover is async by its nature, but we block on its future; because of
this, we need a big thread pool (namely, rebalance scheduler).
Switching to async mode of operation for partition moving will allow us to
shrink the rebalance scheduler size drastically, ideally to just 1 thread as it
will now only execute light, non-I/O, non-CPU-heavy tasks.
> Do not block on PartitionMover future
