Instant Relief from Slow MySQL Reporting Queries using DynamoDB
+2 Vote Up -2Vote Down

Here’s the scenario. You’ve got a table in MySQL for reporting that has a few million rows, and is denormalized for reporting. You’ve got a Pentaho Report that is querying this MySQL table. You have two problems with the current report.

  1. Your users are complaining that the query is slow, and they have to wait around for longer than they’d like to see their report. (approx 40s)
  2. Your DBAs are cranky because they see the size of this table is getting bigger. (approx 1.8GB)

MySQL is fundamentally designed to be an OLTP database and …

Employee +0 Vote Up -0Vote Down

I get several emails each week that are from folks who have the basics mechanics of being a DBA but are looking to learn how to manage data. They can administer a database server but want to know how to get more out of that data. I now have an excellent book for them to refer.

My copy of Pentaho Solutions: Business Intelligence and Data Warehousing with Pentaho and MySQL arrived last week. I need to disclose that I was originally hired by MySQL to replace one of this books authors, Roland Bouman. He told me a year ago that he was …

"Pentaho Solutions": copies hit the mail
+6 Vote Up -0Vote Down

Hi!

Just a few hours ago, I arrived home after a very quiet and peaceful two-week holiday with my family. It was great! I didn't bring a computer on purpose. I brought a mobile phone, but didn't answer that on purpose too :) Result: absolute relaxation, with lots of time to hike, cycle, and read, and occasional visits to musea and historic sites. Bliss :)

Anyway, now that the bags are unpacked, and the kids are asleep, it's time to face the dragon better known as my inbox. What I found brought a big smile to my face:

Starring Sakila: MySQL university recording, slides and materials available onMySQLForge
+0 Vote Up -0Vote Down

Hi!

Yesterday I had the honour of presenting my mini-bi/datawarehousing tutorial "Starring Sakila" for MySQL University. I did a modified version of the presentation I did together with Matt Casters at the MySQL user's conference 2009. The structure of the presentation is still largely the same, although I condensed various bits, and I added practical examples of setting up the ETL process and creating a Pentaho Analysis View (OLAP pivot table) on top of a Mondrian Cube.

The slides, session recording, and materials such as SQL …
