SkySQL Cloud Data Suite - Enterprise meets the Cloud

Look! You can see the heart beating!


In case you are wondering, no, nobody in the family is expecting another baby…


I thought I had to start the post with this picture. Today I feel a bit like the day I went to the hospital for a pregnancy scan. As you may expect, seeing the baby moving was incredibly emotional, and I can feel some similar emotions with this announcement.


Many of you already know that today SkySQL has announced and will release the very first version of our very first product, the

Avoiding a MySQL Data Blackout in Amazon
+0 Vote Up -0Vote Down
MySQL data rules the cloud, but recent experience shows us that there's no substitute for maintaining copies of data, across availability zones, when it comes to Amazon Web Services (AWS) data resilience. In this video (recording of our 8/23/12 webcast), we survey technologies for maintaining real-time copies of your data and the pros & cons of each. We conclude with a live demonstration of a
Amazon EC2 now powered by high performance storage (benchmark)
+3 Vote Up -0Vote Down

A while ago I had a discussion with someone about the future of server infrastructure. Among other things, we were wondering whether companies will continue to run on dedicated servers or if eventually everyone just ends up in a Cloud environment. During the discussion I raised a point that in principle Cloud is a great idea that will keep attracting more and more people, but it is missing one important piece that stops many from using it – a high performance storage. Apparently, this has just changed.

Yesterday I received an e-mail announcing a new EC2 instance type – hi1.4xlarge. It features 16 logical CPUs (35 ECUs), 60GB of RAM, and… two 1TB SSD-based disk volumes! These are great specs that should work for nearly any database. Even assuming someone has a MySQL database larger than 2TB, not all tables will

MySQL on S3: performance with storage located across the continent
+2 Vote Up -0Vote Down

Can OLTP database workloads use Amazon S3 as primary storage? Now they can, thanks to the Cloud Storage Engine (ClouSE), but the question is: how fast?


To answer the question about performance, we decided to run db_STRESS benchmark on a MySQL database in Amazon EC2.  We compared 3 configurations:

  • “Across the street storage”: ClouSE with data stored in S3 in the same region (US Standard)

OblakSoft is pleased to announce the release of ClouSE version 1.0b.1.2 and WordPress on S3 / Yapixx refresh.

This release addresses performances and usability issues reported by our early adopters.  Thank you all for your feedback.

  • Support for MySQL 5.5.25

Now ClouSE supports MySQL thru 5.5.25.  To keep the distribution small, we don’t build binaries for MySQL prior to 5.5.14 anymore.  If you need one, please contact us.

  • Weblob content type improvement

Now the content type for Weblobs is set based on their name.  Previously, the content type for all Weblobs was set to application/octet-stream, which could lead to undesirable Web Browser

At a time when most companies are doing all they can to maintain the status quo, SkySQL is daring to imagine a new “normal”. We’re on a mission to change the way companies interact with and manage their data, both in the enterprise and in the cloud. Along with our strategic partners, in particular MariaDB, we’re working to develop new open source database solutions that challenge proprietary enterprise solutions and business models.

To help us achieve our goal, we’re looking for a few daring open source engineers to join our team and take on the status quo:

Why shared-storage DB clusters don't scale
+4 Vote Up -2Vote Down
Yesterday I was asked by a customer for the reason why he had failed to achieve scale with a state-of-the-art "shared-storage" cluster. "It's a scale-out to 4 servers, but with a shared disk. And I got, after tons of work and efforts, 130% throughput, not even close to the expected 400%" he said.

Well, scale-out cannot be achieved with a shared storage and the word "shared" is the key. Scale-out is done with absolutely nothing shared or a "shared-nothing" architecture. This what makes it linear and unlimited. Any shared resource, creates a tremendous burden on each and every database server in the cluster.

In a previous post, I identified database engine activities such as buffer management, locking, thread locks/semaphores,

Install and configure MySQL on EC2 with RedHat Linux
+1 Vote Up -0Vote Down

Recently I had to turn a few EC2 instances into MySQL database servers. The third time I had to do it, I grabbed the list of steps from my previous sessions and just replayed it. Later I thought maybe polishing information a little bit and publishing a step-by-step walkthrough on the blog may help a few people. So here it is.

Before you begin.

For my MySQL instances I used the following:

  • Extra Large, High-Memory, and High-CPU instances. Although the instruction should work on any type of instance.
  • RedHat Enterprise Linux 6.2 64-bit AMI
  • For MySQL data storage, multiple identical EBS devices attached to each instance

The configuration template provided in this post assumes the new MySQL instance only needs InnoDB storage engine.

Grab the packages.

WordPress on S3: the beauty of simplicity
+2 Vote Up -1Vote Down

My first computer program was written almost quarter a century ago on a BK-0010 computer.  It was very simple: the program asked the user to enter their name and then greeted the user using the entered name, like “Hello, Artem!”.  I was fascinated.  A couple of lines written in Vilnius BASIC transformed a piece of metal and silicon into a considerate thing that cared about a person’s name enough to remember it :-).  Of course, the first experience doesn’t represent the day-to-day routine of software development, but the moments when I see a couple of lines making an amazing transformation still enchant me, and remind me why I’ve been writing code all this time.

I’ve just experienced this very same first-time feeling as we’ve released

Interesting behavior of a MySQL benchmark on EC2
+0 Vote Up -0Vote Down

I had to benchmark an EC2 instance to see whether a database could be safely moved to it. It is a good practice, which helps avoiding surprises when an instance or its storage are allocated in a noisy neighborhood, where the neighbors use so much resources that it affects the performance of our MySQL database. It is understandable that one can never get very reliable results on EC2, this is a shared environment after all, and that some fluctuations should be expected, however it is still good to know the numbers. I started my benchmarks and everything seemed fine at first, but then sometimes statistics I was getting started looking quite odd.

I was running the benchmarks on a High-CPU Extra Large Instance and couldn’t see any reliability in the results at all. I mean, in one moment I was getting poor throughput and horrible response

Impressions from Amazon's AWS Summit in NYC
+0 Vote Up -0Vote Down
Yesterday (4/19) I attended the AWS Summit in NYC (http://aws.amazon.com/aws-summit-2012/nyc).

I'm a big fan and also a heavy user of AWS especially S3, EC2, and naturally, RDS. In every point in time I have several dozens of AWS machines running for me out there in the East region, and in some cases when we do some special benchmarks and tests, number of EC2 and RDS machines can easily reach 3-digit. As I said, I'm a fan...

A few quotes I was able to catch and document on my laptop, on my laps...:
"When you develop an app for facebook, you must be prepared (and be afraid) that to your party, not noone will show up, but everybody will show up!"
So true! Simple and true. We all want to succeed, to have success with our app. We have to think about scaling

MySQL Conference 2012 Day 0
+0 Vote Up -0Vote Down

Wow! A lot has changed since the last MySQL conference I blogged about in 2007.

MySQL has been acquired twice: once as MySQL by Sun and the second time around bundled with Sun when Oracle bought Sun. The conference is no longer organized by O’Reilly but by Percona. And the MySQL database itself has changed — we were talking about new features in MySQL 5.1, which wasn’t released yet, along with Falcon (where did it go?). 5.1 has long since been released as has 5.5, and we’re now talking about 5.6 instead of 6.0. There was no “Cloud” on the horizon, nor was there MariaDB, XtraDB, Drizzle, Schooner, or any of the other offshoots of MySQL, all of which are creating a new buzz around the product.

Yet, one thing remains constant: the vibrant community around MySQL.

We've all seen cloud computing discussed ad nauseam on blogs, on Twitter, Quora, Stack Exchange, your mom’s Facebook page... you get the idea. The tech bloggers and performance experts often pipe in with their graphs and statistics showing clearly that dollar-for-dollar, cloud hosted virtual servers can’t compete with physical servers in performance, so why is everyone pushing them? It's just foolhardy, they say.
