DataStax has released its first version of DSBench in DataStax Labs, a tool designed for model validation, performance and scale testing for Cassandra and DSE. It allows users to run tests against DataStax Enterprise (DSE) or Apache Cassandra, validate data models, incorporate scale testing into continuous integration practices, and more. The tool is free and aims to be accessible to everyone with a common set of concepts and standard configuration format. DSBench focuses on workloads - data, operations, and access patterns - and doesn't require compilation or large amounts of test data. It also has built-in instrumentation that can integrate with most metrics systems. DataStax encourages users to provide feedback for future improvements.
