MDBX is compact, fast, powerful, and robust and implements a simplified variant of the BerkeleyDB API. In fact libmdbx is revised and extended descendant of Lightning Memory-Mapped Database (aka LMDB). Permissive non-copyleft BSD-style OpenLDAP Public License 2.8. Русскоязычная версия этого README здесь. libmdbx is superior to LMDB in terms of features and reliability, not inferior in performance. In comparison to LMDB, libmdbx makes many things just work perfectly, not silently and catastrophically break down. libmdbx supports Linux, Windows, MacOS, FreeBSD and other systems compliant with POSIX.1-2008.
