About:
LMDB is an ultra-fast, memory-mapped key-value database designed for read-heavy workloads. It offers ACID transactions with MVCC concurrency, providing simple, reliable data storage with minimal overhead. Its zero-copy API and tiny footprint make it ideal for embedded systems and high-performance applications.
Key Features:
  • Extremely high read performance
  • Memory-mapped storage (zero-copy)
  • ACID transactions with MVCC
  • Tiny codebase and library size
  • Single-writer, multi-reader concurrency
Use Cases:
  • High-performance caching layers
  • Embedded database for applications
  • Identity and directory services
  • Configuration and state storage
Alternatives:
  • RocksDB – More feature-rich but higher complexity and overhead
  • SQLite – SQL interface with different performance characteristics
