## Persistent constructor for Aristo DB
## ====================================
##
## This module automatically pulls in the persistent backend library at the
## linking stage (e.g. `rocksdb`) which can be avoided for pure memory DB
## applications by importing `./aristo_init/memory_only` (rather than
## `./aristo_init/persistent`.)
