Why is Aerospike’s HMA-based storage engine so performant?

Aerospike's Hybrid Memory Architecture (HMA) storage engine is designed to deliver unmatched speed and reliability, making it a game-changer for demanding applications such as real-time ad targeting, e-commerce recommendation engines, and financial trading systems. By combining the best aspects of in-place and out-of-place update architectures, Aerospike achieves unparalleled performance in both reads and writes. The primary index is stored entirely in memory, enabling efficient reads and high-throughput writes, while garbage collection is simplified through a straightforward and efficient process that minimizes overhead. This design delivers the write efficiency of LSM trees while ensuring predictable, low-latency reads, critical for real-time applications.
