Executive Summary

Fast indexing requires the leaves of a Fractal Tree® Index to be big. But some queries require the leaves to be small in order to get any reasonable performance. Basements nodes are our way to achieve these conflicting goals, and here I’ll explain how.

Big Leaves

On many occasions, we at Tokutek have pointed out that TokuDB is write optimized, which means TokuDB indexes data much faster than a B-tree solution such as InnoDB. As with any write-optimized data structure, Fractal Tree indexes need to bundle up lots of small writes into a few big writes. Otherwise, there’d be no way to beat a B-tree. So the question is, how big do the writes have to be?

Consider how long it takes to write k bytes to a disk. First, there is the seek time s, which we can assume to be independent of k. Next, once we’ve moved the disk head somewhere, we need to write the bytes, which …

I’ll be attending this year’s US based Open Database Camp from June 8-10 in Charlotte, NC. The conference is co-located with SouthEast LinuxFest 2012.

It appears that OpenSQL Camp was renamed Open Database Camp since I see many database technologies listed on their site that do not use SQL as an access method. The final schedule of presentations shows lots of MySQL content for Friday. There is one session each for MySQL, PostgreSQL, and MongoDB on Saturday. Sunday is “unconference” style, hopefully we can get more variety in those sessions.

I love attending this type of conference because I learn how real-world users are implementing MySQL to meet their needs. It also gives me a chance to see some …

The signal-to-noise ratio in the NoSQL world has made it hard to figure out what’s going on, or even who has something new. For all the talk of performance in the NoSQL world, much of the most exciting part of what’s new is really not about performance at all.

Take for example, MongoDB, which has a really great data model and MapReduce has a very handy scripting language. These are genuine and probably long-lasting contributions. Their innovation is all about finding a new language to use for interacting with data. They are about NoSQL.

The confusion comes, for me, when we get to the performance side of the equation. I explore this in detail in an article I did for Datanami recently – http://www.datanami.com/datanami/2012-05-22/the_sound_and_the_nosql_fury.html.

Martin Farach-Colton and I ran a Tutorial on Algorithms for Memory Sensitive Computing on May 18th at the 44th ACM Symposium on Theory of Computing (STOC) at NYU. Here is the program for the tutorial.

Erik Demaine (MIT) spoke on the History of I/O Models. Throughout the years, a remarkable variety of computational models have been proposed to explain the effects of caching, data locality, prefetching, and single-and multi-level memory hierarchies. Erik traced the intellectual history and connections between these models. Most approaches now sit on shelves. (For example, lower bounds on the cache and I/O …

TokuDB® is a proven solution that scales MySQL® and MariaDB® from GBs to TBs with unmatched insert and query speed, compression, and online schema flexibility.

Tokutek’s recently launched TokuDB v6 delivers all of these features and more, with the introduction of high performance replication for MySQL and MariaDB. TokuDB v6 eliminates the common and persistent problem of “slave lag” in which a replication server is unable to keep up with the query load borne by the master server. TokuDB v6 solves this by offering high ingestion rates at the slave.

Many database management tasks become difficult as you move from millions of rows and gigabytes of data to billions of rows and terabytes of data. Such tasks include ingesting data while maintaining indexes; changing schemas without downtime; and supporting connections, replication, and backup. For some scaling problems (connections and replication), MySQL® is better than most of the competition. For others, such as indexing, schema changes, and backup, MySQL has typically been harder to use. Fortunately, the tasks MySQL does well are in its core, whereas the tasks that are more difficult can be solved with storage engine plug-ins.

I recently gave a talk at IOUG Collaborate, a copy of which can be found here. This …

Tackling machine data on the ground to ensure successful operations for NASA in space

We are excited to have Gerry Narvaja start today at Tokutek! Gerry has spent more than 25 years in the software industry, most of them working with databases for different kinds of applications, from embedded to large-scale web products. Gerry worked first at MySQL, and then Sun Microsystems supporting the Sales teams. In 2008 he transitioned into being a Senior MySQL DBA. Gerry graduated as an Electronic Engineer from I.T.B.A (Instituto Tecnológico de Buenos Aires) and has an M.B.A. from Universidad del Salvador in collaboration with S.U.N.Y.A (State University of NY at Albany).

Gerry enjoys helping users to solve complex database production issues. For almost a year he has been co-hosting the popular MySQL Community podcast, OurSQL, which was given the …

In April, I got to give a talk at Percona Live, about why The Right Read Optimization is Actually Write Optimization. It was my first industry talk, so I was delighted when someone in the audience said “I feel like I just earned a college credit.”

Box offered to host everyone’s slides from the conference here (mine is here). A big thanks from me to Sheeri Cabral, for recording my talk and posting it online!
