In Application and Database Design, Small Things Can Have a Big Impact

With modern application design, systems are becoming more diverse, varied and have more components than ever before. Developers are often forced to become master chefs adding the ingredients from dozens of different technologies and blending them together to create something tasty and amazing. But with so many different ingredients, it is often difficult to understand how the individual ingredients interact with each other. The more diverse the application, the more likely it is that some seemingly insignificant combination of technology may cause cascading effects.

Many people I talk to have hundreds if not thousands of different libraries, APIs, components, and services making up the systems they support. In this type of environment, it is very difficult to know what small thing could add up to something much bigger. Look at some of the more recent …

Comparing AMD EPYC Performance with Intel Xeon in GCP

Recently we were asked to check the performance of the new family of AMD EPYC processors when using MySQL in Google Cloud Virtual Machines. This was motivated by a user running MySQL in the N1 machines family and willing to upgrade to N2D generation considering the potential cost savings using the new AMD family. 

The idea behind the analysis is to do a side-by-side comparison of performance considering some factors: 

  • EPYC processors have demonstrated better performance in purely CPU-based operations according to published benchmarks. 
  • EPYC platform has lower costs compared to the Intel Xeon platform. 

The goal of this analysis is to check if cost reductions by upgrading from N1 to N2D are worth the change to avoid suffering from performance problems and eventually reduce the machine size from the current 64 cores based (N1 n1-highmem-64 – Intel Haswell) to either N2D 64 …

Failover comparison in Aurora MySQL 2.10.0 using proxySQL vs Aurora’s cluster endpoint

 

Aurora cluster promises a high availability solution and seamless failover procedure. However, how much is actually the downtime when a failover happens? And how proxySQL can help in minimizing the downtime ? A little sneak peek on the results ProxySQL achieves up to 25x less downtime and the impressive up to ~9800x less errors during unplanned failovers. How proxySQL achieves this: 

  1. Less downtime
  2. “Queueing” feature when an instance in a hostgroup becomes unavailable.

So what is ProxySQL? ProxySQL is a middle layer between the database and the application. ProxySQL protects databases from high traffic spikes, prevents databases from having high number of connections due to the multiplexing feature and minimizes the impact during planned/unexpected failovers or crashes of DBs. 

This blog will continue with measuring the impact of an unexpected …
