5 Performance tips for running Galera Cluster for MySQL or MariaDB on AWS Cloud

Amazon Web Services is one of the most popular cloud environments. Galera Cluster is one of the most popular MySQL clustering solutions. This is exactly why you’ll see many Galera clusters running on EC2 instances. In this blog post, we’ll go over five performance tips that you need to take under consideration while deploying and running Galera Cluster on EC2.

Monitoring Galera Cluster for MySQL or MariaDB - Understanding and Optimizing IO-related InnoDB metrics

This blog post is a follow up to our previous post on monitoring CPU-related InnoDB metrics in Galera Cluster. One of the main issues in terms of scalability of MySQL (and thereby also Galera) is the ability to handle large amounts of I/O activity. MySQL, historically, was not very good in this area - flushing caused bumps and spikes in the workload, and kernel mutex was wrecking havoc in the overall stability.

SQL Load Balancing Benchmark - Comparing Performance of MaxScale vs HAProxy

In a previous post, we gave you a quick overview of the MaxScale load balancer and walked through installation and configuration. We did some quick benchmarks using sysbench, a system performance benchmark that supports testing CPU, memory, IO, mutex and also MySQL performance. We will be sharing the results in this blog post.

Deep Dive Into How To Monitor MySQL or MariaDB Galera Cluster - Live Webinar April 21st

If you’re in Operations and your job is to monitor the health of MySQL/MariaDB Galera Cluster or Percona XtraDB Cluster, then this webinar is for you. Setting up a Galera Cluster is fairly straightforward, but keeping it in a good shape and knowing what to look for when it’s having production issues can be a challenge.

How to Deploy and Configure MaxScale for SQL Load Balancing with Read-Write Split

There are two models of load balancing: transport and application layer. HAProxy is a great TCP load balancer, but it’s lack of SQL awareness effectively limits its ability to address certain scaling issues in distributed database environments. In the open source world, there’s been a few SQL-aware load balancers, namely MySQL Proxy, ProxySQL and MaxScale, but they all seemed to be in beta status and unfit for production use. So we were pretty excited when the MariaDB team released a GA version of MaxScale earlier this year. In this blog, we’ll have a look at MaxScale and see how it compares with HAProxy.

Monitoring Galera Cluster for MySQL or MariaDB - Understanding and Optimizing CPU-related InnoDB metrics

The performance of a Galera cluster is strongly connected to the performance of MySQL. Galera only supports the InnoDB storage engine, it is therefore important to have an insight into how InnoDB operates  what metrics we can rely on and what kind of issues we might face. In this blog post, we will give you a tour of some of the InnoDB internals. Note that we covered Galera monitoring and host/OS monitoring in previous blogs.

Monitoring Host Metrics of your Database Instances - How to interpret Operating System Data

Monitoring the metrics of the database hosts is critical. By keeping Swap and Physical Memory usage within allowable limits, you’ll ensure that there is enough memory for queries to be executed and connections to be created. By monitoring Disk Utilization, you can map growth patterns and better plan for capacity upgrades.
