Via SpamExperts:
SpamExperts has their own anti-spam filtering cloud which is provided as a software-as-a-service (SaaS) model. In addition they have an e-mail security product which they install, update and monitor on-site. Most of SpamExperts’ anti-spam technology has been developed in-house and makes extensive use of the MySQL database. All clients contribute in real-time to their filtering effectiveness, so they have many different data flows that are handled by MySQL. Replication is used to synchronize the data between the systems in a cluster and to push data feeds in real-time. The SaaS cloud is replicated across four countries for redundancy, whereas client installations spread the data retrieval around the globe.

As Hakan mentioned previously, the full text of SQL-99 Complete, Really by Peter Gulutzan and Trudy Pelzer, is now in the AskMonty.org Knowledgebase. Importing the text and formatting it for the Knowledgebase was a major project and I’m glad that it’s done.
Having the full text of this book freely available is a great thing for anyone who uses SQL because the book is about the SQL-99 standard and not about any particular database implementation. They do talk about different implementations, but those sections are clearly marked as such, and serve as examples of how some databases implement (or diverge from) the standard.

In our upcoming MariaDB 5.3 release Monty optimized the internal string append code for performance. I tested his patch with a plain MariaDB 5.2 vs. a patched MariaDB 5.2 with sql-bench, which showed an overall performance gain around 3%.
The details of the patch Monty describes like this
Patch to optimize string append:
While examining a trace output from a mysql-test-run case, I noticed a
lot of reallocation calls. This was strange as MariaDB/MySQL was
designed to do so few malloc/realloc as possible. The system uses was
to first calculate how big buffer you would need and then allocate a
buffer big enough for most usage. …

I was happy to see the announcement yesterday from Tokutek regarding their addition of MariaDB to their list of supported platforms for the TokuDB storage engine.
One particular item in the press release caught my eye: “Our customers are choosing MariaDB more and more frequently for their most demanding database applications.” We’ve added many new features over the past year in our various 5.1 and 5.2 releases, but beyond the new goodies we’ve focused a lot of energy on removing bugs and improving performance. We’ve known for a while that MariaDB is the best version of MySQL out there; …
There has been a lot happening in the MariaDB community recently, and there has been growth. Here are some of the highlights. Thank you to all our current contributors, and to others that want to contribute, shoot community[at]askmonty[dot]org an e-mail.

I am happy to announce that MariaDB 5.2.3 is now released as a stable release.
During the gamma period we did not receive any serious reports for issues in 5.2, so we are relatively confident that the new code is of decent quality.
You can read about the features of MariaDB 5.2 in my previous blog entry or in the fast growing MariaDB knowledgebase..
What is most interesting about MariaDB 5.2 is that most of the features came from the MariaDB/MySQL community, not from Monty Program Ab!
Without the community it would not have been possible to do a stable release so soon after the last release. …
