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 …

on Wednesday November 15, 2017, we bring you a webinar double bill.

Join Percona’s Chief Evangelist, Colin Charles as he presents “The Proxy Wars – MySQL Router, ProxySQL, MariaDB MaxScale” at 7:00 am PST / 10:00 am EST (UTC-8).

Reflecting on his past experience with MySQL proxies, Colin will provide a short review of three open source solutions. He’ll run through a comparison of MySQL Router, MariaDB MaxScale and ProxySQL and talk about the reasons for using the right tool for an application.

In this blog post, we’ll look at how ProxySQL improves MySQL SSL connection performance.

When deploying MySQL with SSL, the main concern is that the initial handshake causes significant overhead if you are not using connection pools (i.e., mysqlnd-mux with PHP, mysql.connector.pooling in Python, etc.). Closing and making new connections over and over can greatly impact on your total query response time. A customer and colleague recently educated me that although you can improve SSL encryption/decryption performance with the AES-NI hardware extension on modern Intel processors, the actual overhead when creating SSL connections comes from the handshake when multiple roundtrips between the server and client are needed.

With ProxySQL’s support for SSL on its backend connections and connection pooling, we can have it sit in front of any application, on the same server (illustrated below):

This post is the third of a series focusing on the MySQL high availability solutions available in 2017.

The first post looked at the elders, the technologies that have been around for more than ten years. The second post talked about the adults, the more recent and mature technologies. In this post, we will look at the emerging MySQL high availability solutions. The “baby” MySQL high availability solutions I chose for the blog are group replication, proxies and distributed storage.

Group replication

Group replication is the Oracle response to Galera. The term “InnoDB cluster” means a cluster using group replication. The goal is offering …

Welcome to another post in our series of interview blogs for the upcoming Percona Live Europe 2017 in Dublin. This series highlights a number of talks that will be at the conference and gives a short preview of what attendees can expect to learn from the presenter.

This blog post is with Avraham Apelbaum, DBA and DevOps at Wix.com His talk is titled Orchestrating ProxySQL with Orchestrator and Consul. The combination of ProxySQL and Orchestrator solves many problems, but still requires some manual labor when the configuration changes when there is a network split (and other scenarios). In our …
