Announcing iiBench for MySQL in Java
+0 Vote Up -0Vote Down

I just pushed the new Java based iiBench for MySQL (and Percona Server and MariaDB), the code and documentation are available now in the iibench-mysql Github repo. Pull request are welcome!

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 …

CIS Oracle MySQL 5.6 Security Benchmark
+1 Vote Up -0Vote Down

I've been working on the CIS security benchmark for Oracle MySQL 5.6. There already is a benchmark document for earlier versions of MySQL.

The benchmark document helps you to ensure you have a secure configuration for MySQL.

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 …

MySQL 5.6 Performance on POWER8
+0 Vote Up -0Vote Down

The following sentence is brought to you by IBM Legal: The postings on this site are my own and don’t necessarily represent IBM’s positions, strategies or opinions.

My previous post covered the work needed to get MySQL 5.6.17 running reliably on modern POWER systems. The patch to MySQL 5.6.17 that’s needed is available here.

For those who don’t know, POWER8 is the …

Interview with John Partridge, President & CEO of Tokutek, Inc.
+0 Vote Up -0Vote Down

“As the database gets used, shards can grow at an uneven rate and one shard might carry a majority of the load. MongoDB corrects this by balancing shards, but because of MongoDB’s lack of concurrency this operation can stall the database unacceptably.”–John Partridge.

I have interviewed John Partridge, President & CEO of Tokutek, Inc.

RVZ

Q1. Tokutek recently announced to have eliminated performance issues of MongoDB sharding. What was the problem?

When it’s faster to use SQL in MySQL NDB Cluster over memcache API
+3 Vote Up -0Vote Down

Memcache access for MySQL Cluster (or NDBCluster) provides faster access to the data because it avoids the SQL parsing overhead for simple lookups – which is a great feature. But what happens if I try to get multiple records via memcache API (multi-GET) and via SQL (SELECT with IN())? I’ve encountered this a few times now, so I decided to blog about it. I did a very simple benchmark with the following script:

#!/bin/bash
mysql_server="192.168.56.75"
mc_server="192.168.56.75"
mysql_cmd="mysql -h${mysql_server} --silent --silent"
mysql_schema="percona"
mysql_table="memcache_t"
mc_port=11211
mc_prefix="mt:"

TokuDB vs Percona XtraDB using Tokutek’s MariaDB distribution
+1 Vote Up -0Vote Down

Following are benchmark results comparing Tokutek TokuDB and Percona XtraDB at scale factor 10 on the Star Schema benchmark. I’m posting this on the Shard-Query blog because I am going to compare the performance of Shard-Query on the benchmark on these two engines. First, however, I think it is important to see how they perform in isolation without concurrency.

Because I am going to be testing Shard-Query, I have chosen to partition the “fact” table (lineorder) by month. I’ve attached the full DDL at the end of the post as well as the queries again for reference.

I want to note a few things about the …
