Episode 371: Howard Chu On the Lightning Memory-Mapped Database (LMDB)

Howard Chu, CTO of Symas Corp and chief architect of the OpenLDAP project, discusses the key technical features of the Lightning Memory-mapped Database (LMDB) that make it one of the fastest, most efficient, and safest embedded data stores in the world. Host Gavin Henry spoke with Chu about B+tree data structures, multi-version concurrency control, memory-mapped files, code efficiency, LDAP, copy-on-write, crash recovery, database speed, code size, and the decision factors of building something from scratch after assessing and discounting alternatives.
