If I use rocksdb for all 3 of index-store, document-store, and tx-log, is it prudent to use separate instances of rocks db for each of those? It seems that way it would be easier to rebuild the indices if needed or to swap out rocksdb for an alternative in the future.

@jtlocsei Yes, exactly. It's always advisable to use 3 separate instances. This is another good question we can answer with the upcoming simplest-possible-config doc. 🙂 Thanks for highlighting it again.
