If you ever had to deal with performance and/or disk space issues related to temporary tables, I bet you eventually found yourself puzzled. There are many possible scenarios depending on the type of temporary table, settings, and MySQL version used. We have observed a pretty long evolution in that matter due to a couple of reasons. One of them was the need to completely eliminate the need to use the deprecated MyISAM engine, and at the same time introduce more performant and reliable alternatives. Another set of improvements was required related to InnoDB, where it was necessary to lower the overhead of temporary tables using that engine.

For that reason, I decided to gather them in a sort of summary which may help to troubleshoot their usage. Due to vast changes between major MySQL releases, I divided the article by them.

In this post I’d like to explain a big optimization in CRC-32C computation, inspired by a paper by Gopal, V., et al.: “Fast CRC computation for iSCSI Polynomial using CRC32 instruction” from Intel, which landed in MySQL 8.0.27 and hugely increases the processing speed (the improvement for ARM64 architectures is more pronounced for reasons explained […]

In a serverless world, traditional databases scale differently. They need a rock solid foundation that Vitess and PlanetScale can provide.

Overview Identity is a critical component of security. The OCI MySQL Database Service (MDS) enables DBAs to leverage existing OCI User Identites and Group Memberships for authentication into MySQL Database Service Instances, providing increased security, centralized management, and ease of use.  Using this feature, an MDS instance can validate a connecting user via the users OCI IAM API Key.   This enables DBAs to centrally manage MDS […]
