Introducing Data Fabric Design for Commodity SQL Databases
+2 Vote Up -0Vote Down

Data management is undergoing a revolution.  Many businesses now depend on data sets that vastly exceed the capacity of DBMS servers.  Applications operate 24x7 in complex cloud environments using small and relatively unreliable VMs.  Managers need to act on new information from those systems in real-time. Users want constant and speedy access to their data in locations across the planet.

It is tempting to think popular SQL databases like MySQL and PostgreSQL have no place in this new world.  They manage small quantities of data, lack scalability features like parallel query, and have weak availability models. …

The MySQL Community: Beleaguered or Better than Ever?
+4 Vote Up -1Vote Down

The  MariaDB Foundation announcement spawned some interesting commentary about the state of open source databases.  One recent headline cited the "beleaguered MySQL community." Beleaguered is a delightful adjective.  The OED tells us that it means beset, invested, or besieged.  Much as I like the word, I do not think it is an accurate or useful description of the MySQL community. …

Hand holding PostgreSQL on a simple query
+0 Vote Up -0Vote Down

With MySQL it was for a long time the case that a lot of sub queries would actually perform poorly, because of poor execution plans. (This is no longer the case in MariaDB 5.5 or the upcoming MySQL 5.6.) Because of this, any MySQL DBA knows the rule of thumb that sub-queries should basically be avoided and you can usually get the same result by using JOINs instead.

I've now learned why PostgreSQL DBAs like sub queries so much. PostgreSQL - being the most advanced open source database - apparently does the exact opposite optimizations as MySQL: it requires you to rewrite simple queries into complex subqueries to get what you want. (Update: Mark …

MySQL and PostgreSQL faces at Froscon
+0 Vote Up -1Vote Down

My three previous blog posts I already wrote from Froscon. In this post I still want to go back and mention some people I met and discussions I had.

The MySQL side

There were of course many MySQL people, with both SkySQL and Oracle sponsoring. It was great to meet Carsten from Oracle, who has joined the MySQL Sales Engineer team in Europe (he moved from an OpenOffice position). That's my former team, so it was great to see a new face!

Going there the person I was most looking forward to meet was Hana Hütter, formerly a MySQL account manager for Central Europe, and now doing the same at SkySQL. My first ever MySQL sales gig …
