Database systems with hybrid operational and analytical data processing (HOAP) architectures are gaining popularity. These first appeared in the relational world, and the CH-benCHmark (CH) was proposed in 2011 to evaluate such systems. Today, NoSQL database systems are gaining adoption for new applications. This session presents CH2, a new benchmark aimed at evaluating hybrid data platforms in the document data management world.
Like CH, CH2 borrows from and extends both TPC-C and TPC-H. Differences from CH include a document-oriented schema, a data-generation scheme that creates a TPC-H-like history, and a "do-over" of the CH queries that is more in line with TPC-H. You’ll learn about the design of CH2, and see the preliminary results from running CH2 against Couchbase Server 7.0. The results provide insight into the performance isolation and horizontal scalability properties of Couchbase Server 7.0 and demonstrate the efficacy of CH2 for evaluating hybrid NoSQL database systems.
