In a recent benchmark conducted on Google Compute Engine, Couchbase Server 3.0 outperformed Cassandra by 6x in resource efficiency and price/performance. The benchmark sustained over 1 million writes per second using only one-sixth as many nodes and one-third as many cores as Cassandra, resulting in 83% lower cost than Cassandra.
We at Couchbase have been actively taking part in that discussion, because we believe open, transparent benchmarks are a valuable tool for demonstrating that a specific NoSQL database can support a specific use case under a specific set of conditions. Benchmarks are an important tool to show potential customers how a vendor’s product can support the customer’s application requirements and can scale as those requirements evolve.
