The only rules for the hackday are: make something cool, keep it simple, document it, learn something and have fun. In general it means time is […]

I have a difficult task of making this post interesting, helpful and personal at the same time. I think the main goal is to balance these aspects, and I really appreciate your comments and suggestions that I will add here.For the busy readers who may be put off by the length of this post, here is a very short summary: I spent 4 wonderful years, first as the head of Field Services, then as a CTO, I believe it is now time for a change, so I am leaving SkySQL. I am leaving behind a great company and very good friends, but I am not disappearing completely, and I will continue supporting the work I started and the projects I created with the help of such great people.For many, leaving a company is not easy, and it is extremely difficult if you have contributed to its creation and development since the beginning. Even more difficult is to depart  [Read more...]
Script to manage MaxScale
+1 Vote Up -0Vote Down
MaxScale 1.0 from SkySQL is now in Beta and there are some cool features in it, I guess some adventurous people has already put it into production. There are still some rough edges and stuff to be fixed, but it is clearly close to GA. One thing missing though are something to manage starting and stopping MaxScale in a somewhat controlled way, which is what this blog is all about.

I have developed two simple scripts that should help you manage MaxScale in a reasonable way, but before we go into the actual scripts, there are a few things I need to tell you. To begin with, if you haven't yet downloaded MaxScale 1.0 beta, you can get it from MariaDB.com, just go to Resources->MaxScale and to get to the downloads you first need to register (which is free). Here are downloads to

MariaDB Replication, MaxScale and the need for a binlog server
+2 Vote Up -0Vote Down

Introduction

This is an introduction to MariaDB Replication and to why we need a binlogs server and what this is. The first part is an introduction to replication basics, and if you know this already, then you want want to skip past the first section or two.

MariaDB Replication

MySQL and MariaDB has a simple but very effective replication system built into it. The replication system is asynchronous and is based on a pull, instead of a push, system. What this means in short is that the Master keeps track of the DML operations and other things that might change the state of the master database and this is stored in what is called the binlog. The slave on the other hand is responsible for getting the relevant information from the master to keep up to speed. The binlogs consist of a number of files that the master generates, and the traditional

MaxScale 1.0-beta is out - Happy Birthday MaxScale!
+2 Vote Up -0Vote Down
It was a year ago, on a nice Sunday night of the English Summer (apologies for the oxymoron), that Mark Riddoch came to see me and together we headed to the Vansittart Arms, our local family pub round the corner. A pint of London Pride on one side and a Honey Dew on the other were the perfect add-on to Mark’s MacBook Pro, on which Mark was showing me the 0.1 version of MaxScale. It was the result of the joint efforts of Mark’s team, Massimiliano and Vilho, who had worked hard to bring to life the first version of something that I believe will be a natural addition to clusters of  [Read more...]

MariaDB Roadshow Helsinki

One could say that MariaDB originates from Finland’s capital Helsinki. In fact so does MySQL. It was in the Helsinki area that MySQL saw daylight. It was here that Monty Widenius laid the ground for MySQL already in the 80’s, maybe even 1979, when he created UNIREG from which parts were reused when he together with the other 2 founders of MySQL released the first version of MySQL in 1995.

Last week, 19 years later, a MariaDB event was held in Helsinki. It was SkySQL that arranged the first in a row of this year’s MariaDB Roadshow events. The agenda included a walkthrough of

MaxScale 0.7.0 Overview and Highlights
+1 Vote Up -0Vote Down

MaxScale 0.7.0 was recently released (it is the 4th alpha, with the beta on the near horizon), and is available for download here.

The release contains a number of new enhancements as well as 8 bugs fixes.

Enhancements:

  • Galera Support: Enhanced support for Galera cluster to allow Galera to be used as a High Available Cluster with no write contention between the nodes. MaxScale will control access to a Galera Cluster such that one node is designated as the master node to which all write operations will be sent. Read operations will be sent to any of the remaining nodes that are part of the cluster. Should the currently elected master node fail MaxScale will automatically promote one of the remaining nodes to become the new master node.

    +1 Vote Up -0Vote Down

    MaxScale 0.6.0 was recently released (it is the 3rd alpha, with the beta on the near horizon), and is available for download here.

    The particular release only contains 2 great additions and 2 important fixes (and note development continues with the 1.0 (GA) features, but these have not been put into this alpha version).

    Important Additions:

  • A feature-complete read/write splitting module, i.e. read and write operations are now balanced in a smarter way to master or slave servers.
  • New client-based features, such as a version string that provides compatibility with the major connectors, the ability to connect through the root user and the use of the Unix socket when MaxScale is co-located with a client application on the same server.
  • Important Bug
