Tim.CallaghaniiBench measures the rate at which a database can insert new rows while maintaining several secondary indexes. We ran this for 1 billion rows with TokuDB and InnoDB starting last week, right after we launched TokuDB v5.2. While TokuDB completed it in 15 hours, InnoDB took 7 days. The results are shown below. At the end of […]
Thanks again to Sheeri Cabral for having me at the Boston MySQL Meetup on Monday for the talk on “Fractal Tree® Indexes – Theoretical Overview and Customer Use Cases.” The crowd was very interactive, and I appreciated that over 50 people signed up for the event and left some very positive comments and reviews. In addition, the conversation spilled […]
At next month’s Boston MySQL Meetup, I will give a talk: “Fractal Tree Indexes – Theoretical Overview and Customer Use Cases.” The meetup is 7 pm Monday, January 9th, 2012, and will be held at MIT Building E51 Room 337e (corner of Ames & Amherst St, Cambridge, MA). Thanks to host Sheeri Cabral for the […]

The release also addresses a number of other bugs and fixes such as “point update” and “replace into” deadlocks. For more details, see the release notes section of the user’s […]
I’ve been benchmarking and testing TokuDB for a few months now. One goal of benchmarking is to understand what is limiting the performance of a particular configuration. I frequently use “show engine [innodb/tokudb] status;” from within the MySQL command line client as part of my research. As I run most of my benchmarks on InnoDB […]
I’m creating a library of benchmarks and test suites that will run as part of a Continuous Integration (CI) process here at Tokutek. My goal is to regularly measure several aspects of our storage engine over time: performance, correctness, memory/CPU/disk utilization, etc. I’ll also be running tests against InnoDB and other databases for comparative analysis.
