Who am I?

My name is Ákos Lévai, I work in Teradata environments since 2000.
I am Teradata V2R5 master and my focus area is Teradata performance optimization.

Goal of this blog

My experience is that Teradata is a mysterious black box for lots of users and even developers: sometimes it is a lightning fast rocket, but sometimes as slow as a snail.
But really do not know why.

If we look behind the scenes, everything gets clear. My goal is to demystify Teradata and help my fellows to easily write effective SQLs instead of suffering from lack of resources or keep buying new hardware.

This blog is not a theoretical lecture will not explain algorithms, but discusses practical problems and solutions in the following structure:

• What is the problem?
• How to identify it?
• What is the solution?

This blog is not a structured tutorial. The topics are sorted randomly, in the order they came into my mind.
Search if you are interested in a specific topic, or read through for just getting useful tricks and ideas.

Comments are welcome!

So let's uncover the mysteries...
