The Aurora hash join feature for relational databases has been around for a while now. But unlike MySQL Block Nested Loop algorithm, an Aurora hash join only caters to a specific number of use cases. When implemented with the optimizer properly, they can provide great benefits with certain workloads. Below we’ll see a brief example of a quick win.

This new feature is available in Aurora lab mode version 1.16. Because this is a lab feature, it’s important to make sure to test your queries before upgrading, especially if you are looking to scale up to the new R4 instances before the Superbowl to avoid hitting the same problem I discuss below.

When lab mode is enabled and

hash_join

  is ON, you can verify the optimizer feature from the

In this blog, we’ll look at how to monitor Amazon Aurora using Percona Monitoring and Management (PMM).

One impact of the growth of web services such as AWS on DBAs is the need to understand and report on database and application resource usage. DBAs have always had to monitor for performance-related usability issues, which may have led to investment in larger servers. However, services such as Aurora operate pricing models based on usage. Performance issues can be more closely attributed to rising costs, so badly performing systems more visibly affect the bottom line. DBA has become a cost center!

With that in mind, from Percona Monitoring and Management (PMM) 1.5 onwards, we delivered features that provide enhanced support for the performance monitoring of Amazon Aurora instances. “[Aurora] is a fully managed, …

Fill out a quick survey on your cloud data plans.

Today, keeping your enterprise agile and flexible is not just an advantage, it is a requirement. Many of the systems and processes once controlled by businesses onsite are moving offsite to “service” models. This includes Platform as a Service (PaaS), Software as a Service (SaaS), Infrastructure as a Service (IaaS), Database as a Service (DBaaS), etc.

These services are usually referred to as being in the cloud. The enterprise using the service doesn’t maintain or manage the infrastructure of the service in question.

Migrating database workloads to the cloud can be a vital part of improving customer experience, gaining deeper business insights and increasing efficiency. More enterprises are …

In this blog post, we’ll discuss migrating data from encrypted Amazon MySQL RDS to encrypted Amazon Aurora.

One of my customers wanted to migrate from an encrypted MySQL RDS instance to an encrypted Aurora instance. They have a pretty large database, therefore using mysqldump or a similar tool was not suitable for them. They also wanted to setup replication between old MySQL RDS and new Aurora instances.

Spoiler: this is possible without any logical dump.

At first, I checked Amazon’s documentation on encryption and found nothing about this type of …
