Series Introduction

Back in 2016 I decided to write a blog series on InnoDB in hopes that it would help give a good description of the high level mechanics of the storage engine. The main motivating factor at that time was that I knew there was a lot of information out there about InnoDB, but a lot of it was ambiguous or even contradictory and I wanted to help make things a bit clearer if I could.

Now there’s a new storage engine that’s rising in popularity that I feel needs similar attention. Specifically MyRocks, the log-structured merge-driven RocksDB engine in MySQL. Given the amount of discussion in the community about MyRocks, I’m sure most of you already have some degree of familiarity, or at the very least have heard the name.

Now we’ve arrived at a point where this is no longer just a Facebook integration project and major players in the community like Maria and Percona have their own implemented …

We’re pleased to share our webinar “Multi-Region AWS Aurora vs Continuent Tungsten for MySQL & MariaDB”, recorded live on Thursday, April 18th, 2019.

Our colleague Matt Lang walks you through a comparison of building a global, multi-region MySQL / MariaDB / Percona cloud back-end using AWS Aurora versus Continuent Tungsten.

If you’d like to find out how multi-region AWS Aurora deployments can be improved – then this webinar is for you!

We hope you enjoy it!

I have never been proficient in Galera clusters and related technologies, and thus I hadn’t given much thought to Percona Xtradb Cluster (PXC), until Alkin approached me at FOSDEM, and proposed to extend dbdeployer features to support PXC. He mentioned that many support engineers at Percona use dbdeployer) on a daily basis and that the addition of PXC would be welcome.

I could not follow up much during the conference, but we agreed on …
