Scalability Happiness – A Quiet Query Log

Join 7500 others and follow Sean Hull on twitter @hullsean.

There’s a lot of talk on the web about scalability. Making web applications scale is not easy. The modern web architecture has so many moving parts. How can we grapple with the underlying problem?

Also: Why Are MySQL DBAs So Hard to Find?

The LAMP stack scales well

The truth that is half right. True there are a lot of moving parts, and a lot to setup. The internet stack made up of Linux, Apache, MySQL & PHP. LAMP as it’s called, was built to be resilient, dynamic, and scalable. It’s essentially why Amazon works. Why what they’re doing is possible. Windows …

Using Connector/Python with SQLAlchemy

SQLAchemy has support for MySQL Connector/Python for a while now. Here is a little HOWTO showing how install both, and setup a database engine.

There are multiple ways of installing both projects, but here is the simplest using pip, whatever platform you use:

shell> pip install SQLAlchemy
shell> pip install mysql-connector-python 

Start your SQLAlchemy engines using a URL pointing to Connector/Python. Note the connect_args argument which passes extra connection arguments to Connector/Python. In the following example we set the MySQL session variable time_zone …

Building a MySQL Private Cloud: Step 1

Building clusters is usually a fun time. Here’s one of my setups at the Equinix LAX1 facility that is being used for VPN services, OpenVZ clustering, and general RADIUS and MySQL clustering integration. Once the clustering design is finalized, it’s still in flux state while I try out different setups, I’ll post some physical+logical architecture diagrams to show “How to Build a Fault Tolerant Infrastructure for Virtualized MySQL NDB Cluster + Python-based VPN systems.” Stay tuned for more.

OpenVZ and Amazon S3: how to solve the dreaded connection throttle failure

Sometimes we encounter odd application responses that seem to make no sense. One of these such issues is related to running virtual server instances (OS Containers not Para-Virtualized VMs) and attempting to back up their data to Amazon’s S3 cloud storage. For moderately sized virtual machines running MySQL databases or Python/PHP based websites and code repositories this can be an inexpensive, quickly provisioned, and easy way to provide disaster recovery backups in numerous geographic locations, since we generally want DR content to be located in a physically distant location. Nevertheless, we can encounter errors if using an S3 mount in a distance location from our server if the timezone/sync data is incorrect.

The commonly seen error is as follows – and it doesn’t give much information for troubleshooting and resolution.

WARNING: Upload failed:  ([Errno 32] Broken pipe)
WARNING: Retrying on lower speed (throttle=0.00) …

[updated] Free book February returns – Get a copy of the InnoDB Quick Reference Guide

This month is a special month. It’s not because of President’s Day or even the exciting day where we revel in groundhogs. No, this month is special because the free book give-away is happening again. This is where you, the reader, gets to win something free for doing nothing more than posting a comment saying that you want a copy of my recently published book – The InnoDB Quick Reference Guide from Packt Publishing. The book is a great reference for DBAs, PHP, Python, or Perl programmers that integrate with MySQL and want to learn more about the InnoDB database engine.

So, all you have to do is post a comment here saying that you want a copy and write out a single (or more) sentence about how you use InnoDB in your development or production environment. At the end of the month two readers will be chosen via a random list sorting script that …
