Continuent Announces Database Performance Test Tool

Posted on Dec. 4, 2007

San Jose, Calif. – December 4, 2007 – Continuent, Inc., the leading provider of commercial open source middleware solutions for database high-availability and scalability, today announced the release of Bristlecone, a new open source framework for load testing of databases and database clusters. Bristlecone includes two easy-to-run tools designed for comparative evaluations of database performance:

Evaluator generates mixed loads of inserts, updates, deletes, and selects. Output can be built-in graphics, HTML, XML, or CSV.

Benchmark runs performance test cases with systematically varying parameters. Output can be HTML or CSV.

Bristlecone includes support for multi-threaded tests, can generate new tests quickly with simple configuration file changes, and has the ability to perform systematic tests across different database implementations. Bristlecone has been tested against PostgreSQL, MySQL® and HSQLDB.

“Bristlecone is the principle load-testing tool for Continuent's uni/cluster, a commercial database clustering product based on the Sequoia open source project,” says Robert Hodges, CTO at Continuent. “Bristlecone is a great tool because it can work easily with many types of databases. We are also working with the open source community as well as advanced clustering research projects like GORDA to develop off-the-shelf benchmarks of database clusters that anyone can set up and run quickly in their own environments.”

Bristlecone is available at http://bristlecone.continuent.org.
