While Domas may have rather effictively trolled the discussion with his post on howto configure table/user statistics (which gave me a good chuckle I do have to say), it’s at least incorrect for Percona Server as you have to enable the “userstat” server option :)

That being said, once enabled there are no extra configuration variables to think about. This is a huge advantage over configuring PERFORMANCE_SCHEMA - which has a total of THIRTY configuration options (31 if you include the global enable/disable option).

Some of these thirty odd configuration variables are only going to matter if you’re loading your own plugins, and even then, it’s probably only going to matter if they use the MySQL mutex implementations rather than, …

Next week is the Percona Live MySQL Conference and Expo 2013.

Davi Arnaut and I are co-presenting InnoDB: A journey to the core, based on my InnoDB blog series by the same name. We will (fairly quickly) cover InnoDB’s storage formats as described in those posts, but in an interactive format. There will be some new material that hasn’t been blogged yet (mostly stuff that is more difficult to explain or has been incompletely described in innodb_diagrams). Most importantly, Davi and I will be available for questions, and hopefully some of the InnoDB developers …

Spatial data is being more used and needed at a larger number of applications. This type of data is not always easy to be managed or queried. And sometimes calculations need to be done in the application code instead of doing them at the server. Recently we added a new class to manage spatial data with Connector/Net, so our users can have the option to handle spatial data operations at their application code.

Highlights: Foreign Keys, NoSQL JavaScript Connector, MySQL 5.6 and Auto-Tuned Clustering
The MySQL team at Oracle are excited to announce the immediate availability of the second MySQL Cluster 7.3 Development Milestone Release (DMR)
Some might call MySQL Cluster 7.3 “the foreign keys release” – and sure enough it is a major engineering achievement to build a distributed database that enforces referential integrity across a shared-nothing cluster, while maintaining ACID compliance and cross-shard JOINs. But MySQL Cluster 7.3 is a lot more as well. 
The design focus has been on enabling developer agility – making it simpler and faster than ever to enhance new services with a highly scalable, fault tolerant, real-time database – with minimum development or operational effort. 
The key enhancements …

The MySQL Cluster team are working on a new NoSQL JavaScript connector for MySQL. The objectives are simplicity and high performance for JavaScript users:

- allows end-to-end JavaScript development, from the browser to the server and now to the world's most popular open source database

- native "NoSQL" access to the storage layer without going first through SQL transformations and parsing.

Node.js is a complete web platform built around JavaScript designed to deliver millions of client connections on commodity hardware. With the MySQL NoSQL Connector for JavaScript, Node.js users can easily add data access and persistence to their web, cloud, social and mobile applications.
