A blog series about ProxySQL and Galera…

This post is the first of a series of blogposts on how to easily use ProxySQL to scale-out your application’s database workload on a Galera cluster. This series will explore the main concepts in configuring ProxySQL for Galera across three articles as follows:

– A first introductory post describing the minimal configuration needed for ProxySQL to monitor and manage a Galera Cluster.
– A second post describing how to setup a read/write split configuration for our Galera Cluster, using ProxySQL query rules.
– A third and final post with examples on specific cluster configuration options and more detailed explanations on why and how ProxySQL changes the nodes states based on configuration changes and monitored variables. Requirements

To illustrate how to configure ProxySQL for a Galera Cluster we will use a sample Galera Cluster …

MySQL uses connection and config parameters from a number of possible sources. The easiest way to find out where it is looking for config files is to run

$ mysql --help | grep cnf
                      order of preference, my.cnf, $MYSQL_TCP_PORT,
/etc/my.cnf /etc/mysql/my.cnf /Users/kkoehntopp/homebrew/etc/my.cnf ~/.my.cnf

As can be seen, my version of the MySQL client checks in this order

• /etc/my.cnf
• /etc/mysql/my.cnf
• /Users/kkoehntopp/homebrew/etc/my/cnf
• ~/.my.cnf

The cnf file is a file in dot-ini syntax, so you have [groups] and each group contains lines with key = value pairs. Which groups are read?

$ mysql --help | grep "groups are"
The following groups are read: mysql client

So in my case, I would create a /Users/kkoehntopp/.my.cnf looking like this:

[client] …

The MySQL UNIQUE constraint is often used in a column definition in which we need each value for that column to be distinct from the others. Perhaps it is an email column for an on-line registration form and we want to ensure that users cannot register twice for an account using the same email. Whatever the case may be, UNIQUE is there to help us ensure this type of data integrity or business requirement. What if the target table already exists and you determine you need to add a UNIQUE constraint to an existing column? In this post, I will cover 2 ways you can implement a UNIQUE constraint on existing columns using the phpMyAdmin web interface…

In this post I describe the various steps that allowed me to reach 3.6 million queries per second on a single VM instance using MySQL 8.0 with the help of Dynimize.

It's not every day that you get to break a record. So when I discovered that you can now rent by the hour massive instances within Google Compute Cloud that support 224 virtual cores based on AMD EPYC 2 Rome processors, I had to jump at the opportunity to see what kind low hanging fruit might be out there. Low and behold I found it! Oracle's performance record for MySQL on a single server stands at 2.1M QPS without using Unix sockets, and 2.25M QPS with Unix sockets. Seeing that they published this 3 years ago on Broadwell based …
