since 2017, and many customers have used it with great success while we collected requirements for the next iteration of our Lambda extension. Much of what’s covered in this blog post is taken from that talk. A cold start occurs when there’s no instance of the requested Lambda function available.

This blog was originally published in July 2017 and was updated in August 2023. Check out this blog to learn how to avoid disaster! This means that multiple partitions can be processed simultaneously, making better use of available hardware resources and further enhancing query performance. So, What is MySQL Partitioning?

On multi-core machines – which is the majority of the hardware nowadays – and in the cloud, we have multiple cores available for use. The queries are similar to those I’ve used in older blog posts comparing MySQL and Apache Spark performance ( [link] ). With faster disks (i.e. AWS Aurora (based on MySQL 5.6)

So far I’ve read a gazillion blog posts about people’s experiences with these AI coding assistance tools. was available as a single self-contained file that I could directly include into my extension without using a package manager like npm or a bundler like webpack (the fewer external tools I needed to set up, the better!).

This weeks’ blog post covers a technique you can use to make all file operations on Windows run at one tenth their normal speed (or slower), in a way that will be untraceable for most users! When you own all of the code then this may involve some back of the envelope estimates, competitive benchmarking, or intuition tuned by experience.

Back in 2014, I started a series of blog posts here to talk about specific wait types and what they do and don’t mean. These threads are created when SQL Server starts, depending on the number of processor cores available for SQL Server to use. If you’re reading this and thinking “what is he talking about?” then this post is for you.

To simulate text messages I have used ~3 billion of reddit comments (10 years from 2007 to 2017), downloaded from pushshift.io. Vadim published a blog post about analyzing reddit comments with ClickHouse. With the latest ClickHouse version, all of these features are available, but some of them may not perform fast enough.
