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 …

Fun with Bugs #42 - Bugs Fixed in MySQL 5.7.12
+0 Vote Up -0Vote Down

MySQL 5.7.12 was released more than 2 weeks ago. New features introduced there in a form of "rapid plugins" are widely discussed, but I am more interested in bugs reported by MySQL Community users that are fixed there. Unfortunately I do not see MySQL Community Release Notes by Morgan (like this) for quite a some time, so I have to continue describing key bug fixes and name people who reported and verified bugs in my "Fun with Bugs" series.

MySQL Bug #79497: Full text indexes and aggregate functions
+0 Vote Up -0Vote Down

Playing around with the Employees sample database and full text search on MySQL, I found a weird bug. After creating a full text targeting a column on a table, a "select distinct" query to retrieve the range of values returns an empty set. So if you initially perform the following query, the outcome comes with 7 rows: mysql> select distinct title from titles; +--------------------+ | title

On Upgrades to Percona Server 5.7 GA: Ubuntu 14.04 Case
+0 Vote Up -0Vote Down

After upgrading Percona Server 5.6.28 (and "full stack" of Percona software) to 5.7.10-3 GA on CentOS 6 and building it from Git Source on Fedora Core 23 yesterday, I've decided to spend some time upgrading Percona Server on my netbook that plays a role of "home build/test/VMs server" and runs under Ubuntu 14.04:
openxs@ao756:~$ uname -a
Linux ao756 3.13.0-77-generic #121-Ubuntu SMP Wed Jan …

MySQL Contributions status
+1 Vote Up -0Vote Down

This post is an update to the status of various MySQL bugs (some with patches) that I’ve filed over the past couple of years (or that people around me have). I’m not looking at POWER specific ones, as there are these too, but each of these bugs here deal with general correctness of the code base.

Firstly, let’s look at some points I’ve raised:

On Upgrades to Percona Server 5.7 GA: Building from Git Source on Fedora
+1 Vote Up -0Vote Down

While writing my first post in this series I was bulding Percona Server 5.7 from Git sources on my wife's Fedora Core 23 box based on this manual page, for my collection of test instances. As I build MySQL and related software from sources …

MySQL Support People - Those Who Joined Oracle to Work on MySQL
+1 Vote Up -0Vote Down

In this post I'd like to mention my colleagues from MySQL Support who had joined the team when Oracle already acquired Sun (and MySQL as a part of it), in 2010-2012. There were several really great engineers among them:

MySQL Support People - The Next Generation
+1 Vote Up -0Vote Down

My first post in this series caused quite an active discussion on Facebook. Readers correctly noted some mistakes in dates and missing names in the list. I've corrected some of the mistakes already and will correct some others later. What was also noted is that initially support for MySQL was provided by developers (this is really important, we'll get back to this later), and of them many had never even got a title of Support …

My First Steps in Exploring RocksDB
+0 Vote Up -0Vote Down

RocksDB and storage engine for MySQL based on it (so called "MyRocks") is widely discussed in my circles since August 2015 at least, so I decided to spend some time checking it. The easy way to get it running is to use Facebook's MySQL 5.6, so I just clonned it and built from source with minor customization based on instructions (that just work in case of Fedora Core 23):

Fun with Bugs #41 - Bugs Fixed in MySQL 5.7.11
+0 Vote Up -0Vote Down

I've just noted that Oracle had released new versions of MySQL on February 5, 2016 formally, so while these days I am mostly thinking about the ways to do support properly, remembering my colleagues and trying to understand some of RocksDB internals, it's time to postpone all these and write about bugs again. This time about some of the public bug reports from MySQL Community and Oracle engineers that were fixed by Oracle in MySQL 5.7.11.

As usual, I'll try to mention who had reported a bug and who verified it, as I think that names …
