In MySQL 8.0.0 we introduced many new features; among those, three new functions that ease and enhance the support for working with UUIDs.

Background

A UUID is just a 128-bit value and it is usually represented in human-readable format as an UTF8 string composed of 5 groups of hexadecimal characters separated by dashes.…

I’ve been lately compiling and generating .deb packages for several MySQL and MariaDB recent versions, and I wanted to try them more in depth -specially MySQL 8.0 and MariaDB 10.2, both of which are still in development.

Several people have already given their first impressions (or will do soon), and testing early is the best way to catch bugs and regressions, and get them fixed before the official release. In fact, as I will comment later, I ran into breaking bugs on both MySQL 8.0 and MariaDB 10.2, which I …

In MySQL 8.0.0 we introduced many new features; among those, we extended the bit-wise operations to work with binary data. Because of these changes, storing and manipulating IPv6 addresses can be done in an easier manner. In this blog we will take a look at how can you do this for some of the most common use cases.…

The MariaDB audit plugin is an audit plugin that is bundled with MariaDB server. However, even though it is bundled with MariaDB, the plugin is actually compatible with MySQL as well. In this blog post, I will describe how to install the plugin with MySQL. Install the plugin Unfortunately, neither MariaDB Corporation nor MariaDB Foundation currently distribute a standalone binary ... Read More

Transportable tablespaces for InnoDB tables is a very useful feature added in MySQL 5.6 and MariaDB 10.0. With this new feature, an InnoDB table’s tablespace file can be copied from one server to another, as long as the table uses a file-per-table tablespace. Unfortunately, the initial transportable tablespace feature in MySQL 5.6 and MariaDB 10.0 does not support partitioned tables. ... Read More

Tab housekeeping but I also realise that people seem to have missed announcements, developments, etc. that have happened in the last couple of months (and boy have they been exciting). I think we definitely need something like the now-defunct MySQL Newsletter (and no, DB Weekly or NoSQL Weekly just don’t seem to cut it for me!).

MyRocks

During @scale (August 31), Yoshinori Matsunobu mentioned that MyRocks has been deployed in one region for 5% of its production workload at Facebook.

By October 4 at the …

I neglected to mention my November appearances but I’ll just write trip reports for all this. December appearances are:

• A bit of a Japan tour, we will be in Osaka on the 17th, Sapporo on the 19th, and Tokyo on the 21st. A bit of talk of the various proxies as well as the various servers that exist in the MySQL ecosystem.

Looking forward to discussing …

This blog post discusses the business continuity plan around MySQL backups, and how organizations should think about them.

During the years I’ve worked in IT, I’ve learned that backups sometimes are a conceptual subject in organizations. Many companies have them, but don’t document the associated business continuation plan for them. I experienced this the hard way many many years ago, somewhere around when MySQL 5.0 was still widely used.

In most organizations, there are a couple of business continuity subjects that should be described internally. For example, what is the recovery time objective and what is the recovery point objective. Let’s go a bit deeper into both concepts:

Recovery Point Objective:

A recovery point objective describes the utter limit of time data …

This blog post discusses how better MySQL 8.0 benchmarks can improve MySQL in general.

Like many in MySQL community, I’m very excited about what MySQL 8.0 offers. There are a lot of great features and architecture improvements. Also like many in the MySQL community, I would like to see MySQL 8.0 perform better. Better performance is what we always want (and expect) from new database software releases.

Rarely do performance improvements happen by accident – they require running benchmarks, finding bottlenecks and eliminating them. This is the area where I think things could use improvement.

If you come to the MySQL Keynote at Oracle OpenWorld, or if you go to MySQL …
