Geo-distributed multi-master Galera Cluster on Amazon EC2. Join Codership at Amazon re:Invent Las Vegas 26-29 November

Implementing Galera Cluster on Amazon EC2  provides several advantages for companies. Multi-master clustering comes out of the box as a default in Galera. Users can read and write from any database providing fast local writes and reads. Galera handles conflicts automatically if your application is writing to the same row. Nodes can be added and deleted on the fly if you need more capacity and elasticity. New nodes can join automatically. In the case data center downtime Galera provides disaster recovery and Galera Cluster takes care of the split brain situation too. Automated failover and recovery allow the database to continually service the application transparently.

Meet the developers and experts of Galera Cluster in Amazon re:Invent Las Vegas 26-29 November. You can find us at Venetian hotel, booth number 738.

Maintenance Windows in the Cloud

Recently, I’ve been working with a customer to evaluate the different cloud solutions for MySQL. In this post I am going to focus on maintenance windows and requirements, and what the different cloud platforms offer.

Why is this important at all?

Maintenance windows are required so that the cloud provider can do the necessary updates, patches, and changes to our setup. But there are many questions like:

  • Is this going to impact our production traffic?
  • Is this going to cause any downtime?
  • How long does it take?
  • Any way to avoid it?

Let’s discuss the three most popular cloud provider: AWS, Google, Microsoft. These three each have a MySQL based database service where we can compare the maintenance settings.

AWS

When you create an instance you can define your maintenance window. It’s a 30 minutes block when AWS can update and restart …

Analyzing Amazon Aurora Slow Logs with pt-query-digest

In this blog post we shall discuss how you can analyze slow query logs from Amazon Aurora for MySQL, (referred to as Amazon Aurora in the remaining blog). The tools and techniques explained here apply to the other MySQL compatible services available under Amazon Aurora. However, we’ll focus specially on analyzing slow logs from Amazon Aurora version 2 (MySQL 5.7 compatible) using pt-query-digest. We believe there is a bug in Aurora where it logs really big numbers for query execution and lock times for otherwise really fast queries.

So, the main steps we need are:

  1. Enable slow query logging on your Amazon Aurora DB parameter group, apply the change when appropriate.
  2. Download the slow log(s) that …

Amazon RDS Multi-AZ Deployments and Read Replicas

Amazon RDS is a managed relational database service that makes it easier to set up, operate, and scale a relational database in the cloud. One of the common questions that we get is “What is Multi-AZ and how it’s different from Read Replica, do I need both?”.  I have tried to answer this question in this blog post and it depends on your application needs. Are you looking for High Availability (HA), read scalability … or both?

Before we go to into detail, let me explain two common terms used with Amazon AWS.

Region – an AWS region is a separate geographical area like US East (N. Virginia), Asia Pacific (Mumbai), EU (London) etc. Each AWS Region has multiple, isolated locations known as Availability Zones.

Availability Zone (AZ) – AZ is simply one or more data …
