> For tables with a lot of regions, the ExportSnapshot appears to "hang" without progress cause it copies the .snapshot directory (which has tiny, reference/reference-like files I assume) and does not report its state. Would be good if it dumped its state for like say, every 50 files it copies.
> This operation is also sequential, so takes a lot of time, and can be improved to do 5-10 threads at a time in parallel perhaps, since the actual writes are tiny (i.e. data transfer is no concern) and its mostly just NN interaction that's needed here.
