Seems like few features: 1. sstables as different files 2. range delete (which is rare)

compared to LMDB (which is faster & more efficient): https://symas.com/lmdb/technical/

Still would be nice to see how LMDB would fare in a complex distributed DBMS (most of them are in rocksdb-type libraries).

But LMDB is supposed to stay small. So more features are in a fork: https://github.com/leo-yuriev/libmdbx

LMDB is already used in distributed DBs - such as LDAP. OpenLDAP performance is orders of magnitude greater than any RDBMS or other distributed DB.
