MySQL 5.7 : no more password column!
+1 Vote Up -0Vote Down

Maintaining a project like MySQL::Sandbox is sometimes tiring, but it has its advantages. One of them is that everything related to the server setup comes to my attention rather earlier than if I were an average DBA or developer.

I try to keep MySQL Sandbox up to date with every release of MySQL and (to a lesser extent) MariaDB [1]. For this reason, I am used to trying a new release with MySQL Sandbox, and … seeing it fail.

Of the latest changes in MySQL, probably the most disruptive was what …

Can we output content of a mariaDB table into JSON using the CONNECT Storage Engine ? MariaDB and MySQL are not currently JSON friendly databases. The usage of JSON in MySQL is almost inexistent with the excetion of the explain JSON output and of MariaDB dynamic column dump. There also exist a few udf (in [...]

In MySQL Character encoding – part 1 we stated that the myriad of ways in which character encoding can be controlled can lead to many situations where your data may not be available as expected.

Setting MySQL Client and Server Character encoding.

Lets restart MySQL with the correct setting for our purpose, UTF8. Here …

Table and tablespace encryption on MariaDB 10.1.3
+0 Vote Up -0Vote Down

Introduction

For the moment, the only engines that fully support encryption are XtraDB and InnoDB. The Aria storage engine also supports encryption, but only for temporary tables.

MariaDB supports 2 different way to encrypt data in InnoDB/XtraDB:

  1. Specified table encryption: Only tables which you create with PAGE_ENCRYPTION=1 are encrypted. This feature was created by eperi.
  2. Tablespace encryption: Everything is encrypted (including log files). This feature was created by Google and is based on their …

DbCharmer Development: I Give Up
+0 Vote Up -0Vote Down

About 6 years ago (feels like an eternity in Rails world) working at Scribd I’ve started working on porting our codebase from some old version or Rails to a slightly newer one. That’s when I realized, that there wasn’t a ruby gem to help us manage MySQL connections for our vertically sharded databases (different models on different servers). I’ve started hacking on some code to replace whatever we were using back then, finished the first version of the migration branch and then decided to open the code for other people to use. That’s how the DbCharmer ruby gem was born.

For the next few years a lot of new functionality we needed has been added to the …

MariaDB 10.1.1: triggers for RBR
+2 Vote Up -0Vote Down

Sometimes users ask for something that doesn’t really make sense. On the first glance. But then you start asking and realize that the user was right, you were wrong, and it is, actually, a perfectly logical and valid use case.

I’ve had one of these moments when I’ve heard about a request of making triggers to work on the slave in the row-based replication. Like, really? In RBR all changes made by triggers are replicated from the master to slaves as row events. If triggers would be fired on the slave they would do their changes twice. And anyway, assuming that one only has triggers one the slave (why?) in statement-based replication triggers would run on …

MariaDB 10.1.1: engine_condition_pushdown flag deprecated
+0 Vote Up -0Vote Down

Let me start with a little story. You sit in your house near the fireplace in the living room and need a book from the library… Eh, no, sorry, wrong century. You’re building a robotic arm that will open your beer or brew your coffee or supply you with whatever other drinks of your choice… while you’ll be building the next robotic arm. So, you — soldering iron in one hand and Arduino in another — ask your little brother to bring a box with specific resistors (that you unexpectedly run out of) from the cellar. The problem — your brother is small and cannot tell a resistor from a respirator. You explain that it’s small thing with two …
