Looking deeper into InnoDB’s problem with many row versions
+0 Vote Up -0Vote Down

A few days ago I wrote about MySQL performance implications of InnoDB isolation modes and I touched briefly upon the bizarre performance regression I found with InnoDB handling a large amount of versions for a single row. Today I wanted to look a bit deeper into the problem, which I also filed as a bug.

First I validated in which conditions the problem happens. It seems to happen only in REPEATABLE-READ isolation mode and only …

Should vegetarians open steakhouse restaurants?

"Should vegetarians open steakhouse restaurants?"

Though someone will probably give me several examples of why they should, I'll argue that they absolutely should not. How can someone who doesn't eat steak convince others to eat at their "steak-only" restaurant?

But this is something a "professional technology benchmarker" (PTB) struggles with on a regular basis. Hello, I'm Tim Callaghan, and I'm a PTB.
professional technology benchmarker, or PTB (noun) : One who compares two technologies as part of their job. One of these technologies is usually the product of the PTB's employer, the other is almost …

I'm starting off 2015 with the following New Year's Resolution, to improve the state of benchmarking. About a month ago I noticed the following tweet:
Hey @tokutek, please look at this: http://stssoft.com/products/stsdb-4-0/benchmark …. Are the benchmarks rigged or correctly done? I'm curious to know!While I've never met Ian Campbell (@iamic) he certainly knew how to call me to action. I immediately checked out the …

The history of iiBench goes back to the early days of Tokutek. Since "indexed insertion" is a strength of Fractal Tree indexes, the first iiBench was created …

Benchmark of Load Balancers for MySQL/MariaDB Galera Cluster
+1 Vote Up -0Vote Down

October 31, 2014 By Severalnines

When running a MariaDB Cluster or Percona XtraDB Cluster, it is common to use a load balancer to distribute client requests across multiple database nodes. Load balancing SQL requests aims to optimize the usage of the database nodes, maximize throughput, minimize response times and avoid overload of the Galera nodes. 

In this blog post, we’ll take a look at four different open source load balancers, and do a quick benchmark to compare performance:

TokuMX vs. PostgreSQL in EnterpriseDB's NoSQL Compression Benchmark
+0 Vote Up -0Vote Down

Since this is my first blog I feel it's necessary to introduce myself. I'm Tim Callaghan, I work at Tokutek (makers of TokuDB and TokuMX), and I love benchmarking. While some of the content on this blog will certainly be about Tokutek technologies, I plan on exploring a wide variety of others as well. These are strictly my own personal views and opinions, and comments/feedback are always welcome. Lets get started...

A few weeks ago I …

Testing the Fastest Way to Import a Table into MySQL (and some interesting 5.7 performance results)
+2 Vote Up -0Vote Down

As I mentioned on my last post, where I compared the default configurations options in 5.6 and 5.7, I have been doing some testing for a particular load in several versions of MySQL. What I have been checking is different ways to load a CSV file (the same file I used for testing the compression tools) into MySQL. For those seasoned MySQL DBAs and programmers, you …

Center for Internet Security (CIS) is a nonprofit organization.

The Call For Participation is now open.

If you are already a CIS member then you can download the document here. If you don't have an account you can register for free.

How-to and Performance Impact of SSL-Encrypted Replication Traffic in Galera Cluster for MySQL
+0 Vote Up -0Vote Down

August 7, 2014 By Severalnines

 

Deploying Galera Clusters across WAN environments might lead to concerns around data privacy and security - especially as more organisations are having to comply with national and international regulations. You would not want hackers eavesdropping or intercepting replication traffic. Encrypted replication hides what is sent between the Galera nodes, and makes sure each node is only communicating to the ones it trusts. But how expensive is encryption?

 

In this blog, we will show you how to encrypt the replication traffic between your Galera nodes. We will …
