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 …

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 …

 SCaLE 19X – the 19th annual Southern California Linux Expo – will take place  March 3-6, 2022 in Pasadena, CA. 

SCaLE is the largest community-run open-source and free software conference in North America. It is held annually in the greater Los Angeles area.  A year might have been skipped due to Covid-19 but it looks like we will be back in person this year.  

The MySQL Track features nine talks on a variety of subjects from some of the best  known MySQL experts.

Security will always be a main focal point of a company’s data. A common question I get from clients is, “how do I enable encryption?” Like every good consulting answer, it depends on what you are trying to encrypt. This post is a high-level summary of the different options available for encryption in Percona Server for MySQL.

Different certifications require different levels of encryption. For example, PCI requires both encryptions of data at rest and in transit. Here are the main facets of encryption for MySQL:

• Data at Rest
  • Full disk encryption (at the OS level)
  • Transparent Data Encryption – TDE
  • Column/field-level encryption
• Data in Transit
  • TLS Connections

Data at Rest

Following my post MySQL/ZFS Performance Update, a few people have suggested I should take a look at BTRFS (“butter-FS”, “b-tree FS”) with MySQL. BTRFS is a filesystem with an architecture and a set of features that are similar to ZFS and with a GPL license. It is a copy-on-write (CoW) filesystem supporting snapshots, RAID, and data compression. These are compelling features for a database server so let’s have a look.

Many years ago, in 2012, Vadim wrote a blog post about BTRFS and the results were disappointing. Needless to say that since 2012, a lot of work and effort has been invested in BTRFS. So, this post will examine the BTRFS version that comes with the latest Ubuntu LTS, 20.04. It is not bleeding edge but it is likely the most recent …
