Anybody who has run the MySQL MTR test suite must have seen a statement like “x tests were skipped, y by the test itself. ” at the end of test runs. Why are some tests being skipped? Are the skipped tests affecting test coverage?…

This Log Buffer Edition covers Oracle, SQL Server and MySQL.

I will be at several events in June 2017:

• db tech showcase 2017 – 16-17 June 2017 – Tokyo, Japan. I’m giving a talk about best practices around MySQL High Availability.
• O’Reilly Velocity 2017 – 19-22 June 2017 – San Jose, California, USA. I’m giving a tutorial about best practices around MySQL High Availability. Use code CC20 for a 20% discount.

I look forward to meeting with you at either of these events, to discuss all things MySQL (High Availability, security, cloud, etc.), and how Percona can help you.

As I write this, I’m in Budva, Montenegro, for the Percona engineering meeting.

Back in the days when somebody said MySQL, there was only the MySQL. You could pick different versions (4.0, 4.1) but the vendor was the same. This changed around MySQL 5.0/5.1 when Percona decided to release their own flavour of MySQL - Percona Server. A bit later, MariaDB joined with MariaDB 5.1 and the fun (or confusion) increased. What version should I use? What is the difference between MySQL 5.1, Percona Server 5.1 and MariaDB 5.1? Which one is faster? Which one is more stable? Which one has superior functionality? With time, this got worse as more and more changes were introduced in each of flavours. This blog post will be our attempt to summarize the key features that differentiate them. We will also try to give you some suggestions about which flavour may be the best for a given type of project. Let’s get started.

Many organizations have MySQL or MariaDB databases at the core of their business—for processing and storing product sales, collecting information related to services offered, or just providing essential information to customers. As a result, keeping these databases running continuously can be critical for the success of an organization.

There are many components of a database system that a database administrator will need to consider for maintaining high availability. We considered server equipment (e.g., memory) in a previous introductory article. Now let’s look at using multiple servers for your MySQL and MariaDB databases—let’s look at replication.

Replication Overview

One common and effective way to structure a highly available database system is through some form of database replication. There are a few reasons …
