The MySQL Windows Experience Team is proud to announce the release of MySQL for Visual Studio 2.0.2 m1. Note that this is a milestone release and not intended for production usage.

MySQL for Visual Studio 2.0.2 m1 is the first development release of MySQL for Visual Studio to add support for the new X DevAPI. The X DevAPI enables application developers to write code that combines the strengths of the relational and document models using a modern, NoSQL-like syntax that does not assume previous experience writing traditional SQL.

For more information about how the X DevAPI is implemented in MySQL for Visual Studio, and its usage, please refer to the MySQL for Visual Studio Quick-Start Guide.

Please also note that the X …

You can get many returns from a Google search for “MySQL Query Best Practices” or “MySQL Query Optimization.” The drawback is that too many rules can provide confusing or even conflicting advice. After doing some research and tests, I outlined the essential and important ones below:

1) Use proper data types

1.1) Use the smallest data types if possible

MySQL tries to load as much data as possible into memory (innodb-buffer-pool, key-buffer), so a small data type means more rows of data in memory, thus improving performance. Also, small data sizes reduces disk i/o.

1.2) Use Fixed-length Data Types if Possible

MySQL can calculate quickly the position of a fixed-length column in a specific row of a table.

With the flexible-length data type, the row size is not fixed, so every time it needs to do a seek, MySQL might consult the primary key …

Wednesday night at Percona Live 2016 was reserved for fun, fun, fun! Once again, the Percona Live Game Night proved to be a popular and amazing event. There were more games this year than last, as well as food, drinks, and lots of friendly competition!

This year, besides the ever-crowd-pleasing Meltdown Challenge, there were Segway Races, pool, foosball, shuffleboard, Wii Boxing, Pac-Man Attack, a shootout gallery, darts, as well as virtual reality stations and a death-defying trampoline.

You can see Percona’s CEO Peter Zaitsev demonstrating how you use it, pro-level:

Winning with Open Source Databases

Peter discussed what makes the open source community so vibrant and powerful, and why it is essential to preserve that spirit. Data is critical to the success of your business. You rely on your database and its …

There's a new JSON data type available in MySQL 5.7 that I've been playing with. I wanted to share some examples of when it's useful to have JSON data in your MySQL database and how to work with the new data types (not least so I can refer back to them later!)

MySQL isn't the first database to offer JSON storage; the document databases (such as MongoDB, CouchDB) work on a JSON or JSON-ish basis by design, and other platforms including PostgreSQL, Oracle and SQL Server also have varying degress of JSON support. With such wide adoption as MySQL has, the JSON features are now reaching a new tribe of developers.

Why JSON Is Awesome

Traditional database structures have us design table-shaped ways of storing all our data. As long as all your records (or "rows") are the same shape and have the same sorts of data in approximately the same quantities, this works brilliantly well. There are some common problems that aren't a good …

Congratulations to Ubuntu on releasing 16.04 LTS with MySQL 5.7! As far as I know, it’s the first stable release of a Linux distro that contains MySQL 5.7. Fedora and openSUSE also have MySQL 5.7, but not yet in a stable release.…

On behalf of the entire team, I would like to thank you for stopping by our “meet the MySQL engineering team” BOF held Tuesday night.…

MariaDB 10.1 introduced Data at Rest Encryption. By default we provide a file_key_management plugin. This is a basic plugin storing keys in a file that can be itself encrypted. This file can come from a usb stick removed once keys have been brought into memory. But this remains a basic solution not suitable for security ...continue reading "MariaDB AWS Key Management Service (KMS) Encryption Plugin"

I’ve previously evaluated MariaDB’s 10.1 implementation of data encryption at rest (https://www.pythian.com/blog/data-encryption-rest), and recently did the same for Oracle’s implementation (https://dev.mysql.com/doc/refman/5.7/en/innodb-tablespace-encryption.html) in their MySQL 5.7.

First, here’s a walkthrough of enabling encryption for MySQL 5.7:

1. Install keyring plugin.

1a. Add the following to the [mysqld] section of /etc/my.cnf:

View the code on Gist.

1b. Restart the server:

...
service mysqld restart

1c. Verify:
