There are 3 pillars for a database architecture: Monitoring, Backup / Restore process, High Availability This blog post is about database High Availability; more precisely about one of the best combo of the moment : MySQL 5.7 Group Replication : the only native HA solution for MySQL, it's a Single/Multi-master update everywhere replication plugin for MySQL with built-in automatic distributed recovery, conflict detection and group membership. ProxySQL 1.4 : probably the best proxy for MySQL.

In this post, we’ll look at how to improve queries using generated columns and ProxySQL instead of implementing a referenced table.

Developers and architects don’t always have the time or complete information to properly analyze and design a database. That is why we see tables with more fields than needed, or with incorrect types. The best solution is implementing a change in the database schema and/or application level. In this post, we’ll look at an example of generated columns (using a char field) instead of creating a referenced table, and how using generated columns and ProxySQL avoids changes at the application level.

For this example, I will be using the film table of the Sakila database (with some changes). The original film table had a language_id as tinyint, which refers to the language table:

Let’s look at some of the most popular Percona Database Performance Blog posts in 2017.

The closing of a year lends itself to looking back. And making lists. With the Percona Database Performance Blog, Percona staff and leadership work hard to provide the open source community with insights, technical support, predictions and metrics around multiple open source database software technologies. We’ve had over three and a half million visits to the blog in 2017: thank you! We look forward to providing you with even better articles, news and information in 2018.

As 2017 moves into 2018, let’s take a quick look back at some of the most popular posts on the blog this year.

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

The end of the year is upon us, and this column is being penned a little earlier than usual as I enjoy a quick bout of wrapping up for the year.

We’ve had a lot of things happen in the database world. It’s clear that open source is everywhere, the cloud is large, and we’ve seen a lot of interesting movements in our MySQL world, from the standpoint of corporate contributions too. GitHub continues to enhance Orchestrator, and gh-ost keeps on getting better; Facebook has ensured MyRocks is now mainstream in both MariaDB Server and Percona Server for MySQL distributions; Alibaba Cloud and Tencent have been contributing to make MariaDB Server better. …

Do you need to get to grips with MySQL proxies? Or maybe you could do with discovering the latest developments and plans for Percona’s software?

Well, wait no more because …
