Batch operations using composite keys in postgres over jdbc

Throughout a career as a software developer, you encounter many patterns. Some appear just often enough to remember that they exist, but you still need to look them up every time. I’ve discovered that writing things down helps me remember them more easily. This particular pattern is very useful for my current project. So, it’s time to write it down and hopefully commit it to memory properly this time. Although this post is specific to PostgreSQL, I’m sure other databases have the necessary features to achieve the same results efficiently.

Porting an application from cats effects to ZIO

In my current project, we’re working on a large-ish code base that is written in Scala and uses cats effect as an effect system in large parts of the code base. If you’re not familiar with what an effect system is, I think the most important detail is that it’s a tool that gives you certain superpowers if you promise to be honest about it when your code does things that can be considered “effectful”, such as interacting with the network or reading files. We use the IO monad from cats effect, which is a wonderful way of writing async, concurrent code that looks a lot like synchronous code.
