“For analytical things, eventual consistency is ok (as long as you can know after you have run them if they were consistent or not). For real world involving money or resources it’s not necessarily the case.” — Michael “Monty” Widenius. In a recent interview, I asked Justin Sheehy, Chief Technology Officer at Basho Technologies, maker [...]

I decided to look at subquery optimizations and compare them to what we’ve got in MariaDB 5.3/5.5. In case you don’t know, subquery optimizations in MySQL 5.6 and MariaDB come from a common ancestor - MySQL 6.0 alpha, which was released in spring 2009 and then abandoned because there were too many unstable features pushed into it.

Then, both MariaDB team and Oracle salvaged subquery code out of the 6.0 mess, and worked to get it in shape for release. MariaDB released its results in GA quality in April 2012 as MariaDB 5.3, which was quickly followed by MariaDB 5.5.

Inside MariaDB, we’ve …

“While I believe that one size fits most, claims that RDBMS can no longer keep up with modern workloads come in from all directions. When people talk about performance of databases on large systems, the root cause of their concerns is often the performance of the underlying B-tree index”– Martín Farach-Colton.

Last Month the Verizon folks asked for a presentation on MySQL Replication and so we will have one on Monday October 8th.  MySQL Replication is easy to setup, reliable, and MySQL 5.6 brings some new features such as Global Transaction Identifiers.  So some learn the basics and learn the new features. 

Starts at 5:00 PM! Please do not be late as the doors lock at 5PM and we will have to send someone to check on you!

Refreshments will be served!
