бэкэнд БД с отображением памяти в slapd (Memory-Mapped DB backend to slapd)
Описание (Description)
The mdb
backend to slapd(8) uses OpenLDAP's Lightning Memory-
Mapped DB (LMDB) library to store data. It relies completely on
the underlying operating system for memory management and does no
caching of its own. It is the recommended primary database
backend.
The mdb
backend uses a hierarchical database layout which
supports subtree renames.
