+      LMDB is an ultra-fast, ultra-compact key-value embedded data store
+      developed by Symas for the OpenLDAP Project. It uses memory-mapped files,
+      so it has the read performance of a pure in-memory database while still
+      offering the persistence of standard disk-based databases, and is only
+      limited to the size of the virtual address space.
