Well, it happened again… Another lengthy EBS outage in the US-East region impacted several sites across the net. While failures like this are rare, they can be quite costly and translate into headaches for the operations team when impact production systems for any length of time. At Percona, we routinely help clients architect and deploy [...]
Benchmarking single-row insert performance on Amazon EC2
May 16, 2012 By 17 Comments
I have been working for a customer benchmarking insert performance on Amazon EC2, and I have some interesting results that I wanted to share. I used a nice and effective tool iiBench which has been developed by Tokutek. Though the “1 billion row insert challenge” for which this tool was originally built is long over, [...]
Create 3 nodes XtraDB Cluster in 3 minutes
January 12, 2012 By 1 Comment
I understand that the new technology can be scaring and this makes entry barriers to try and get familiar with it. That’s why I created simple set of scripts which setup N nodes cluster on running EC2 instances. The script assumes that you have running N EC2 instances (in the same availability zone) running RedHat [...]
Making the impossible: 3 nodes intercontinental replication
January 11, 2012 By 29 Comments
In this post I want to show new possibilities which open with Percona XtraDB Cluster. We will create 3 nodes Cluster with nodes on different continents (Europe, USA, Japan) and each node will accept write queries. Well, you theoretically could create 3 node traditional MySQL ring replication, but this is not what you want to [...]
MySQL performance on EC2/EBS versus RDS
August 4, 2011 By 11 Comments
A while ago I started a series of posts showing benchmark results on Amazon EC2 servers with RAID’ed EBS volumes and MySQL, versus RDS machines. For reasons that won’t add anything to this discussion, I got sidetracked, and then time passed, and I no longer think it’s a good idea to publish those blog posts [...]
Shard-Query EC2 images available
May 11, 2011 By 2 Comments
Infobright and InnoDB AMI images are now available There are now demonstration AMI images for Shard-Query. Each image comes pre-loaded with the data used in the previous Shard-Query blog post. The data in the each image is split into 20 “shards”. This blog post will refer to an EC2 instances as a node from here [...]
Should we give a MySQL Query Cache a second chance ?
April 10, 2011 By 64 Comments
Over last few years I’ve been suggesting more people to disable Query Cache than to enable it. It can cause contention problems as well as stalls and due to coarse invalidation is not as efficient as it could be. These are however mostly due to neglect Query Cache received over almost 10 years, with very [...]
MySQL on Amazon RDS part 2: Determining Peak Throughput
March 28, 2011 By 4 Comments
This is a continuation of my series of benchmark posts comparing Amazon RDS to a server running on Amazon EC2. Upcoming posts (probably 6 or 8 in total) will extend the scope of the benchmark to include data on our Dell r900 with traditional hard drives in RAID10, and a server in the Joyent cloud. [...]
MySQL on Amazon RDS part 1: insert performance
March 15, 2011 By 37 Comments
Amazon’s Relational Database Service (RDS) is a cloud-hosted MySQL solution. I’ve had some clients hitting performance limitations on standard EC2 servers with EBS volumes (see SSD versus EBS death match), and one of them wanted to evaluate RDS as a replacement. It is built on the same technologies, but the hardware and networking are supposed [...]
Death match! EBS versus SSD price, performance, and QoS
February 21, 2011 By 55 Comments
Is it a good idea to deploy your database into the cloud? It depends. I have seen it work well many times, and cause trouble at other times. In this blog post I want to examine cloud-based I/O. I/O matters a lot when a) the database’s working set is bigger than the server’s memory, or [...]
