InnoDB vs TokuDB in LinkBench benchmark
+0 Vote Up -0Vote Down

Previously I tested Tokutek’s Fractal Trees (TokuMX & TokuMXse) as MongoDB storage engines – today let’s look into the MySQL area.

I am going to use modified LinkBench in a heavy IO-load.

I compared InnoDB without compression, InnoDB with 8k compression, TokuDB with quicklz compression.
Uncompressed datasize is 115GiB, and cachesize is 12GiB for InnoDB and 8GiB + …

Using Cgroups to Limit MySQL and MongoDB memory usage
+0 Vote Up -0Vote Down

Quite often, especially for benchmarks, I am trying to limit available memory for a database server (usually for MySQL, but recently for MongoDB also). This is usually needed to test database performance in scenarios with different memory limits. I have physical servers with the usually high amount of memory (128GB or more), but I am interested to see how a database server will perform, say if only 16GB of memory is available.

And while InnoDB usually respects the setting of innodb_buffer_pool_size in O_DIRECT mode (OS cache is not being used in this case), more engines (TokuDB for MySQL, MMAP, WiredTiger, RocksDB for MongoDB) …

TokuDB and Binlog Group Commit in MySQL 5.7
+0 Vote Up -0Vote Down

The MySQL 5.7.6 release notes describe a change to the binary log group commit algorithm that can improve the performance of write intensive applications when the binary log is enabled (noted with Bug #19424075).  This change is probably inspired by the experiment reported in MySQL bug #73202.

There is a long history of tweaking the binary log group …

TokuDB and JSON data in MySQL 5.7
+0 Vote Up -0Vote Down


MySQL recently added support for JSON data in an experimental labs version based on MySQL 5.7.7.  It would be cool to store JSON data in TokuDB tables.

First, I had to get TokuDB running on MySQL 5.7.7.   TokuDB currently runs on Percona Server 5.6, and various flavors of MariaDB.  The only issues porting TokuDB to MySQL …

Percona Acquires Tokutek : My Thoughts #3 : Fractal Tree Indexes
+0 Vote Up -1Vote Down

Last week I wrote up my thoughts about the Percona acquisition of Tokutek from the perspective of TokuDB and TokuMX[se]. In this third blog of the trilogy I'll cover the acquisition and the future of the Fractal Tree Index. The Fractal Tree Index is the foundational technology upon which all Tokutek products are built.

LinkBenchX: benchmark based on arrival request rate
+0 Vote Up -0Vote Down

An idea for a benchmark based on the “arrival request” rate that I wrote about in a post headlined “Introducing new type of benchmark” back in 2012 was implemented in Sysbench. However, Sysbench provides only a simple workload, so to be able to compare InnoDB with TokuDB, and later MongoDB with Percona TokuMX, I wanted to use more complicated scenarios. (Both TokuDB and TokuMX are part of Percona’s product line, in the case you missed …

Percona Acquires Tokutek : My Thoughts #1 : TokuDB
+0 Vote Up -0Vote Down

Two weeks ago Percona announced it's acquisition of Tokutek (April 14, 2015). The analyst coverage was a bit fluffy for my liking, but I decided to give it some time and see if anything "meaty" would come along, and ... it hasn't. The sheer number of tweets on Twitter was impressive, which makes me hopeful that the acquisition raised awareness to the Tokutek technologies and that the Tokutek products have a found a good home

I've been thinking a lot about the future of the Tokutek technologies over these same two weeks and want to share them …

Tokutek now part of the Percona family
+0 Vote Up -0Vote Down

It is my pleasure to announce that Percona has acquired Tokutek and will take over development and support for TokuDB® and TokuMX™ as well as the revolutionary Fractal Tree® indexing technology that enables those products to deliver improved performance, reliability and compression for modern Big Data applications.

At Percona we have been working with the Tokutek team since 2009, helping to improve performance and scalability. The TokuDB storage engine has been available for Percona Server for about a year, so joining forces is quite a natural step for us.

Fractal Tree indexing technology—developed by years of data science …

Increasing Cloud Database Efficiency – Like Crows in a Closet
+0 Vote Up -0Vote Down

In Mo’ Data, Mo’ Problems, we explored the paradox that “Big Data” projects pose to organizations and how Tokutek is taking an innovative approach to solving those problems. In this post, we’re going to talk about another hot topic in IT, “The Cloud,” and how enterprises undertaking Cloud efforts often struggle with idea of “problem trading.” Also, for some reason, databases are just given a pass as traditionally “noisy neighbors” and that there is nothing that can be done about it. Lets take a look at why we disagree.

With the birth of the information age came a coupling of business and IT. Increasingly …
