Comparing Replication Technologies for MySQL Clustering: Part 1

Overview The Skinny

Clustering provides high availability and disaster recovery, along with the ability to read-scale both locally and globally. Some clusters even provide active/active capabilities, which others have a single master.

Real time database replication is a must for clustering and other key business purposes, like reporting. There are a number of replication technologies available for MySQL, and some are even bundled into various solutions. When choosing a replication methodology, it is paramount to understand just how the data moves from source to target. In this blog post, we will examine how asynchronous, synchronous, and “semi-synchronous” replication behave when used for clustering. Also, we will explore …

Blog from the Top — What keeps you up at night? Sleep better with Continuent!

Database Administration is a tough, often ungrateful job. Especially if you run a 24/7 business-critical MySQL or MariaDB deployment.

MySQL has proven to be a remarkably solid database which supports billions of dollars in revenue. On some level this very solidity creates a false sense of security. There are many things that can wrong at any given time, whether that is a change to your app, a bug in the database, hardware failure or just simply running out of disk space.

Percona recently conducted a poll: “What keeps you up at night?”

Not surprisingly, “Downtime/HA” is very high on the list.

While there are many challenging issues and tasks that a DBA must deal …

Your Data On The World Wide Web… Forever!

If you share your photos on social media, they will stay on the internet forever…

Many of us have heard or read this sentence during conversations with friends, in articles, online forums, TV shows, etc.

But how is it possible that we can’t seem to be able to fully remove our photos from the internet when we want to, and, taking this further, that our photos are never lost and always retrievable (which can both be a good and a bad thing)?

The behind-the-scenes, technical secret lies in data replication.

The very first moment when you share a photo on social media, that photo is uploaded into the closest available database server. In the second moment, that same photo is replicated into multiple other servers around the world.

This is what data …

Tungsten Clustering versus AWS RDS/MySQL

Enterprises require high availability for their business-critical applications. Even the smallest unplanned outage or even a planned maintenance operation can cause lost sales, productivity, and erode customer confidence. Additionally, updating and retrieving data needs to be robust to keep up with user demand.

Let’s take a look at how Tungsten Clustering helps enterprises keep their data available and globally scalable, and compare it to Amazon’s RDS running MySQL (RDS/MySQL).

Replicas and Failover What does RDS do?

Having multiple copies of a database is ideal for high availability. RDS/MySQL approaches this with “Multi-AZ” deployments. The term “Multi-AZ” here is a bit confusing, as enabling this simply means a single “failover replica” will be created in a different availability zone from the primary database instance. …
