LMDB
Open SourceFundedUltra-fast, compact, crash-proof embedded key-value database
About LMDB
LMDB (Lightning Memory-Mapped Database) is a high-performance, memory-efficient embedded key-value data store designed for applications requiring fast, reliable data access. Developed originally for the OpenLDAP project, LMDB combines the speed of in-memory databases with the persistence of disk-based storage through memory-mapped files. Its compact 32KB object code footprint ensures minimal resource consumption while delivering robust ACID-compliant transactional support with multi-version concurrency control (MVCC).
LMDB is suited for enterprises needing an embedded database that supports fully serialized writers, concurrent multi-thread and multi-process access, and crash-proof reliability without the overhead of logs or recovery procedures. Its maintenance-free design requires no external cleanup or compaction, leveraging the operating system’s buffer cache to optimize performance. Symas offers professional support and porting services to assist organizations in integrating LMDB into their applications, making it a practical choice for enterprise-grade embedded database needs.
