I’ve attached a plain Elisp incremental implementation in
Interface is simply
make-kv-store (path)
compact-kv-store (kv-store)
kv-put (key value kv-store)
kv-get (key kv-store)

But honestly, I suspect using any db as backend for a persistent lisp
store will have virtually no advantage over plain text.
Then why even introduce them at the first place.

The more exciting thing will be to have a general object store
rather than kv-store (aka, incremental for arbitrary mutation
and preserve sharing). Any relational db will not help that either,
and it is better to be done in pure Lisp.
