Description:
Lightning Memory-Mapped Database Utilities
This package provides tools for manipulating LMDB databases: * mdb_stat - LMDB environment status tool * mdb_copy - LMDB environment copy tool . Lighting Memory-Mapped Database (LMDB) is an ultra-fast, ultra-compact key-value embedded data store developed 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, (it is not limited to the size of physical RAM).
