Recently, AWS presented its own CPU on ARM architecture for server solutions.It was Graviton. As a result, they update some lines of their EC2 instances with new postfix “g” (e.g. m6g.small, r5g.nano, etc.). In their review and presentation, AWS showed impressive results that it is faster in some benchmarks up to 20 percent. On the other hand, some reviewers said that Graviton does not show any si
Primary Key design is an important thing for InnoDB performance, and choosing a poor PK definition will have an impact on performance and also write propagation in databases. When this comes to Aurora, this impact is even worse than you may notice. In short, we consider a poor definition of a Primary Key in InnoDB as “anything but quasi sequential values”, which may cause very random access to dat
At some point, your needs for improving database performance may run into a threshold where optimization and tuning are no longer enough. If you cannot change the database engine and can no longer tune the parameters for your workload, you need to use scaling. As it is widely known, scaling may be either vertical or horizontal. Vertical scaling means adding more resources to a single node. Usually

In this post, we’ll look at how to implement ProxySQL with AWS Aurora. Recently, there have been a few discussions and customer requests that focused on AWS Aurora and how to make the various architectures and solutions more flexible. Flexible how, you may ask? Well, there are the usual expectations: How do you improve resource utilization? How can I filter (or block) things? Can I shard with Auro
In the previous blog posts in this series, we’ve covered some of the essential aspects of an Enterprise-grade solution: security, high availability, and backups. Another important aspect is the scalability of the solution: as our application grows how do we accommodate an increase in traffic while maintaining the quality of the service (response time)? The answer to this question depends on the na

If you are a regular reader of this blog, you likely know I like the ZFS filesystem a lot. ZFS has many very interesting features, but I am a bit tired of hearing negative statements on ZFS performance. It feels a bit like people are telling me “Why do you use InnoDB? I have read that MyISAM is faster.” I found the comparison of InnoDB vs. MyISAM quite interesting, and I’ll use it in this post. To
