Couchbase has introduced Plasma, a new high-performance key-value storage engine, as a successor to ForestDB, promising significant advancements in scalability and performance for Couchbase Server 6.0. Unlike its predecessor Memory Optimized Indexes, Plasma is designed to be cost-effective by minimizing reliance on memory, using lock-free data structures to leverage multi-core CPUs, and supporting persistent snapshots for efficient data recovery. Plasma demonstrates superior performance in latency, throughput, and disk efficiency compared to ForestDB, with markedly faster initial and incremental load times. Available exclusively with Couchbase Enterprise Edition (EE), Plasma aims to provide a seamless upgrade for existing users and encourages feedback and engagement through its community forum.
