MySQL Workbench & Performance_Schema

Last week during the Oracle Users Group Leaders Summit in Bucharest I had the pleasure the meet the leaders for the MySQL Users Group from Azerbaijan,  Finland, Madrid and the Netherlands.

During some discussions, it appeared that some users are not aware of the Performance_Schema integration in MySQL Workbench. Indeed with WB you can enable PFS, add sys table if not present by default (<5.7).

You can use a default configuration or customize it and enable all the instruments and consumers you need.

When enabled, you can generate some useful reports

 

 

In case you are also not yet aware of it, the following dashboard is also available in MySQL Workbench

The latest version of MySQL Workbench has been released yesterday, June 13th : 6.3.7 GA

Scaling Percona XtraDB Cluster with ProxySQL in Docker Swarm

In this post, we’ll look at scaling Percona XtraDB Cluster with ProxySQL in Docker Swarm.

In my previous post, I showed how to employ Percona XtraDB Cluster on multiple nodes in a Docker network.

The intention is to be able to start/stop nodes and increase/decrease the cluster size dynamically. This means that we should track running nodes, but also to have an easy way to connect to the cluster.

So there are two components we need: service discovery to register nodes and ProxySQL to handle incoming traffic.

The work with service discovery is already bundled with Percona …

Understand what has changed between MySQL 5.6 and 5.7 before upgrading

MySQL 5.7 has been GA since October 2015. At the time of writing, it is still a very new release. But more and more companies are looking into upgrading, as it has a list of great new features. Schema changes can be performed with less downtime, with more online configuration options. Multi-source and parallel replication improvements make replication more flexible and scalable. Native support for JSON data type allows for storage, search and manipulation of schema-less data.

An upgrade, however, is a complex process - no matter which major MySQL version you are upgrading to. There are a few things you need to keep in mind when planning this, such as important changes between versions 5.6 and 5.7 as well as detailed testing that needs to precede any upgrade process. This is especially important if you would like to maintain availability for the duration of the upgrade.

sync_binlog = 1 in MySQL 5.7

As Morgan announced it his blog post related to new defaults in 5.7, in 5.7.7 and newer the default value of sync_binlog is now 1.

This of course has an impact on performance especially if you don’t have fast storage like a RAID controller with a cache for example.

Already in O’reilly High Performance MySQL, is was written that the most important setting for binary logging on the master is sync_binlog = 1.

And this recommendation was made for MySQL 5.0 ! At that time the performance impact could reach 50%. In 5.6, with the addition of binary log group commit
