16000 active connections – Percona Server continues to work when others die

We just published results with improvements in Thread Pool in Percona Server:
Percona Server: Thread Pool Improvements for Transactional Workloads
Percona Server: Improve Scalability with Thread Pool

What I am happy to see is that Percona Server is able to handle a tremendous amount of user connections. From our charts you can see it can go to 16000 active connections without a decline in throughput.

In fact, in our experiments we used 25000 connections and even more, so I think now we face OS limitations in handling connections as …

Ghosts of MySQL Past: Part 3

See Part 1 and Part 2.

We rejoin our story with a lawsuit. While MySQL suing Progress NuSphere is not perhaps the first GPL lawsuit that comes to mind, it was the first time that the GPL was tested in court. Basically, the GEMINI storage engine was a proprietary storage engine bundled with a copy of MySQL. Guess what? The GPL was found to be valid and GEMINI was eventually GPLed, and it didn’t really go anywhere after that. Why? Probably some business reasons and also, InnoDB was actually rather good and there wasn’t a lawsuit to enforce the GPL there, making business relationships remarkably easier.

In 2003 there was a second round of VC funding. The development team increased …

MySQL, SQL, NoSQL, Open Source And Beyond: a Google Tech Talk

I’ve been invited to give a Tech Talk at Google next Thursday, February 13th, from 11:00 to 12:30 Pacific time. Unfortunately the talk won’t be streamed live, nor is it open to the general public, but it will be recorded and hosted on YouTube afterwards. I’ve also been told that a small number of individuals might be allowed to attend from outside Google. If you would like me to try to get a guest pass for you, please tweet that to @xaprb.

The topic is, roughly, databases. Officially,

MySQL, SQL, NoSQL, and Open Source in 2014 and Beyond

Predictions are hard to get right, especially when they involve the future. Rather than predict the future, I’ll explain how I view the relational and NoSQL database worlds today, especially the MySQL product and community, but including open-source and …

Announcing MySQL Connector/Arduino 1.0.1 Beta

I've completed a new release of the Connector/Arduino. The new version supports a few refinements and a new feature.

  • New! disconnect() method - enables disconnect from server. Note: you must call mysql_connect() to reconnect.
  • Better error handling for dropped packets. No more random reboots when bad packet appears.
  • Library can recover from short-term loss of connectivity. Along with bad packets is a check to make sure what is received is valid making the connector ignore garbage packets associated with a dropped connection.
  • Detection of Out of Memory condition. Should there not be enough memory to allocate the buffer for the Connector, you will see an OOM error (enable the serial monitor to see the errors). This reduces random reboots when memory gets too low.

I made this release because a number of people were running into problems with noisy, tenuous, or just plain …

MaxScale for the rest of us - Part 3

This third post in this series of blogs about MaxScale is finally getting where you want to go: Install and configure MaxScale. The first blog in this series was an overview of what MaxScale is and the second about how to set up a Cluster of MariaDB servers, using MariaDB Replication, for MaxScale to access. But now it's time to introduce MaxScale.

If you skipped the second post as you already know how to set up MariaDB with Replication and all that, be remineded that I will use the same Linux server setup as outlined there even for the MaxScale server and for a client to do some testing, and I recommend you stick with that for now (for MariaDB itself you can use any relevant setup you want, MaxSCale doesn't …

Looking to Hire a MySQL DBA or Developer?

“Why can’t I find an MySQL DBAs or Developers?” This morning I got a message from a very perplexed Human Resources person on why their ads on Linkedin were not getting any results. Several such emails, calls, or messages make it to me each week and I would like take this opportunity to cover this subject. MySQL DBAs and Developers are out there but there are reasons why they are not interested in your job posting.

1. Provide details — “Exciting new position in rapidly growing start up in an expensive city and we want you to know how to program in every programming language, be a recent university graduate (hopefully PhD or higher), with ten years of experience but please be under twenty three years of age. Must prefer stock options and left over pizza crusts over a regular salary. And be flexible.” No, most ads are not quite that bad but several are very, very close.
