Migrating to Amazon Aurora: Optimize for Binary Log Replication

In this Checklist for Success series, we will discuss reducing unknowns when hosting in the cloud using and migrating to Amazon Aurora. These tips might also apply to other database as a service (DBaaS) offerings.

In our previous article, we discussed the importance of continuous query performance analysis, especially in Amazon Aurora where there is less diagnostic visibility compared to running on EC2 or on-premise. Aside from uptime though, we need a lot more from our data, and we definitely cannot isolate it in Aurora.

Next on our checklist is that at one point or another, we will need to use asynchronous replication. Amazon Aurora has an excellent reputation for absorbing intense amounts of …

Migrating to Amazon Aurora: Reduce the Unknowns

In this Checklist for Success series, we will discuss reducing unknowns when hosting in the cloud using and migrating to Amazon Aurora. These tips might also apply to other database as a service (DBaaS) offerings.

While DBaaS encapsulates a lot of the moving pieces, it also means relying on this approach for your long-term stability. This encapsulation is a two-edged sword that takes away your visibility into performance outside of the service layer.

Shine a Light on Bad Queries

Bad queries are one of the top offenders of downtime. Aurora doesn’t protect you against them. Performing a query review as part of a routine health check of your workload helps ensure that you do not miss looming issues. It also helps you predict the …

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 …

This Week in Data with Colin Charles #54: Percona Server for MySQL is Alpha

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

I consider this to be the biggest news for the week: Alpha Build of Percona Server for MySQL 8.0. Experiment with it in a Docker container. It is missing column compression with dictionary support, native partitioning for TokuDB and MyRocks (excited to see that this is coming!), and encryption key rotation and scrubbing. All in, this should be a fun release to try, test, and also to file bugs for!

Database paradigms are changing, and it is interesting to see Cloudflare introducing Workers KV a key-value store, that is eventually consistent and highly distributed (at their global …

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 …

When Should I Use Amazon Aurora and When Should I use RDS MySQL?

Now that Database-as-a-service (DBaaS) is in high demand, there is one question regarding AWS services that cannot always be answered easily : When should I use Aurora and when RDS MySQL?

DBaaS cloud services allow users to use databases without configuring physical hardware and infrastructure, and without installing software. I’m not sure if there is a straightforward answer, but when trying to find out which solution best fits an organization there are multiple factors that should be taken into consideration. These may be performance, high availability, operational cost, management, capacity planning, scalability, security, monitoring, etc.

There are also cases where although the workload and operational needs seem to best fit to one solution, there are other limiting factors which may be blockers (or at least need special handling).

In this blog post, I will try to provide some general rules …
