Best Practices for Configuring Optimal MySQL Memory Usage
+1 Vote Up -0Vote Down

In this blog post, we’ll discuss some of the best practices for configuring optimal MySQL memory usage.

Correctly configuring the use of available memory resources is one of the most important things you have to get right with MySQL for optimal performance and stability. As of MySQL 5.7, the default configuration uses a very limited amount of memory – leaving defaults is one of the worst things you can do. But configuring it incorrectly can result in even worse performance (or even crashes). …

Reserved words usage in MySQL
+0 Vote Up -0Vote Down

It is not uncommon to come across MySQL databases where reserved words are in use as identifiers for any kind of database objects.

Perhaps when the application schema was implemented, the words were not reserved yet, and they became reserved later on a subsequent MySQL release.

It is a good practice to check reserved words usage prior to doing any database upgrades, as any newly reserved keywords will cause syntax errors on the new version.

This is usually not a problem if proper quoting is used for referencing the objects, as described on the official  …

Taking the MySQL document store for a spin
+1 Vote Up -0Vote Down

This is not a comprehensive review, nor an user guide. It's a step-by-step account of my initial impressions while trying the new MySQL XProtocol and the document store capabilities. In fact, I am barely scratching the surface here: more articles will come as time allows.

MySQL 5.7 has been GA for several months, as it was released in October 2015. Among the many features and improvements, I was surprised to see the MySQL team emphasizing the JSON data type. While it is an interesting feature per se, I failed to see the reason why so many articles and …
