LMDB Embedded Database
LMDB is a tiny (<100KB), ultra-fast embedded database. Uses memory-mapped I/O (OS handles paging), ACID transactions, multi-version concurrency. Mastery takes 3-4 weeks. Practitioners earn 15-25% premium because they optimize applications 10-100x faster. The 5% who design LMDB schemas for high-throughput are valuable in fintech, real-time systems.
