Migrate MySQL data to RDS/Aurora Using Xtrabackup

In this blog, I will provide a step by step procedure to migrate from on-premise MySQL to Amazon RDS/Aurora using Percona-xtrabackup

Both RDS and Aurora is a DBAAS provided by Amazon. To know more on DBAAS you can view our presentation here.

When you are having a database in size of few GB, it would be very convenient to take a logical backup using a logical backup tool such as Mysqldump or Mydumper and restore it Amazon RDS/Aurora easily. But this is not the case when you are having a data size of a few hundred GB or TB, Where the logical backup and restore is very painful and time-consuming. To overcome this we can use …

Slow MySQL Start Time in GTID mode? Binary Log File Size May Be The Issue

Have you been experiencing slow MySQL startup times in GTID mode? We recently ran into this issue on one of our MySQL hosting deployments and set out to solve the problem. In this blog, we break down the issue that could be slowing down your MySQL restart times, how to debug for your deployment, and what you can do to decrease your start time and improve your understanding of GTID-based replication.

How We Found The Problem

We were investigating slow MySQL startup times on a low-end, disk-based MySQL 5.7.21 deployment which had GTID mode enabled. The system was part of a master-slave pair and was under a moderate write load. When restarting during a scheduled …

MySQL High Availability Framework Explained – Part I

In this two-part blog series, we will explain the details and functionality of a High Availability (HA) framework for MySQL hosting using MySQL semisynchronous replication and the Corosync plus Pacemaker stack. In Part I, we’ll walk you through the basics of High Availability, the components of an HA framework, and then introduce you to the HA framework for MySQL.

What is High Availability?

The availability of a computer system is the percentage of time its services are up during a period of time. It’s generally expressed as a series of 9′s. For example, the table below shows availability and the corresponding downtime measured over one year.

Availability %

Continuent, helping the big players shine in the market

We are honored to be ranked as one of the 10 fastest growing AWS solution providers to watch in the year 2018 by The Technology Headlines.

Read about our journey, the host of benefits for our customers, our exceptional team, and future roadmap in this Amazon Special Edition.

Delayed Replication with Amazon RDS

Delayed replication” is one of the important features which were being supported in MySQL from 5.6 for a very long time. This induces an intentional lag in the slave, making it lag by the defined time interval.

For a long time this was not available with the RDS version of MySQL provided by AWS, Recently from the version 5.6.40, 5.722 and later versions this feature is available with all the regions.

I will give a small intro on Amazon RDS, Which is DBAAS provided by Amazon, where you will be given an end-point for all your DB operations and major of admin task of server and DB is taken care by Amazon, To know more you can view our presentation here

In this blog, I will demonstrate, how to have a delayed slave with Amazon RDS for MySQL

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 …

The Future Of The Application Stack

Containers are eating the world. If you have built and deployed an application in production over the last few years, the odds are that you have deployed your code in containers. You might have created and deployed individual containers (Docker, Linux LXC, etc.) directly in the beginning, but quickly switched over to a container orchestration technology like Kubernetes (K8s) or Swarm when you needed to coordinate multi-node deployments and high availability (HA). In this container-driven world, what will the future of the application stack look like? Let’s start with what we need from this “future” application stack.

What Do We Need From This Future Application Stack?

Continuent 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 Continuent 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. …
