One of our customers reported that ‘create table select from’ statements stall for a period of time equal to the TokuDB lock timeout. This indicated a lock conflict between multiple transactions. In addition, other MySQL clients that were opening...

When I get to talk to people about TokuMX and how it’s an optimized MongoDB, I sometimes get follow-up questions like: “Is it an in-memory proxy?” “Write optimized? So you buffer all of the writes in memory and lose them on crash?” “Did...

Last week I described TokuDB’s new Hot Backup feature. This week we are going to briefly discuss the same feature, but as it was added to TokuMX, our version of MongoDB. Since the Hot Backup library is essentially a shim between MySQL and the Linux kernel,...

One of our customers sometimes observed lots of simple insertions taking far longer than expected to complete. Usually these insertions completed in milliseconds, but the insertions sometimes were taking hundreds of seconds. These stalls indicated the existence of a...

In talking to existing MongoDB users and TokuMX evaluators, I’ve often heard that the performance of MongoDB is very good as long as your working data set fits in RAM. The story continues that if your working data set grows to be larger than the RAM on your...

We’ve been hard at work on TokuMX since it’s initial release just over 2 months ago. Today we released TokuMX v1.2 which includes Hot Backup in the Enterprise Edition. Hot Backup allows users to create a backup of a running TokuMX primary or secondary...

A common MongoDB tip is to create short field names to save storage space. Because MongoDB does not compress its data on disk and stores field names in each document, using longer field names leads to bigger documents which leads to more storage space usage. The...

Recently, we’ve seen a few people ask us about building TokuMX from scratch. While it’s best if you just use the binaries you can get from us (they have all the right optimizations, we’ve tested them, and we can interpret coredumps they generate), we...

On Wednesday night, the Boston MongoDB User group was kind enough to have me speak about TokuMX Internals. I spoke about Fractal Tree® indexes and the technical reasons behind the benefits they provide to MongoDB applications. Although the talk mostly references...

Since we released TokuMX, one of the most frequent requests has been for a migration tool. TokuMX has a completely different storage format than MongoDB, which means that you have to actually move all of your data out of MongoDB and into TokuMX, you can’t just...

A lot is said about the differences in the data between MySQL and MongoDB. Things such as “MongoDB is document based”, “MySQL is relational”, “InnoDB has a clustering key”, etc.. Some may wonder how TokuDB, our MySQL storage engine, and TokuMX, our MongoDB product,...

In my last post, I showed what a Fractal Tree® index is at a high level. Once again, the Fractal Tree index is the data structure inside TokuMX and TokuDB, our MongoDB and MySQL products. One of its strengths is the ability to get high levels of compression on the...

With our recent release of TokuMX 1.0, we’ve made some bold claims about how fast TokuMX can run MongoDB workloads. In this post, I want to dig into one of the big areas of improvement, write performance and reduced I/O. One of the innovations of TokuMX is that it...

I am actually quite excited about Tokutek’s release of TokuMX. I think it is going to change the landscape of database systems and it is finally something that made me looking into NoSQL. Why is TokuMX interesting? A few reasons: It comes with transactions, and...

Tokutek is known for its full-featured fast-indexing technology. MongoDB is known for its great document-based data model and ease of use. TokuMX, version 1.0, combines the best of both worlds. So what, exactly, is TokuMX? The simplest (but incomplete) answer is that...

Tokutek created the iiBench benchmark back in 2008. The point of the benchmark is to measure the performance of indexed insertions over time. It uses an extremely simple schema, one table with a sequential insertion pattern for the primary key along with three integer...

Over several blog posts, Tim has presented performance results on large data sets of TokuMX, our MongoDB product with fractal tree indexes integrated, side by side with MongoDB. Results look good. We’ve shown improved throughput numbers on a sysbench benchmark,...
