pev2 VS testcontainers-node

This runs in about 250ms. Let's have a look at the explain plan to understand it better. To visualise it, I am using the excellent visualisation tool from Dalibo.

The PEV2 is open source and give you a good visualization. I never used this pgmustard to compare.

Visualize Your Plan: Visit explain.dalibo.com and paste the generated plan text and query. Then, hit Submit. The tool will generate a visualization of your query plan. Here's an example of the visualization for the fifth attempt version of the query from this post. It shows the different types of scans that were used and how the data gets combined. The duration of each operation is also shown:

You can download the whole analyzer as a simple html file and use it this way. No need to obfuscate or sanitize anything at all.

You might be interested in sites like https://explain.dalibo.com/ which make the output a bit nicer to read. I use these quite often to quickly identify bottlenecks.

PostgreSQL Query Plan Analyzer and Visualizer

I didn’t know about pev2, interesting, checking it now. Did you integrate the component yourself or are you using this hosted page by them: https://explain.dalibo.com/?

IMO it‘s important to get started with indexing. Grab your most frequently used queries and run an EXPLAIN ANALYZE to identify the problems. This tool might help you to understand your execution plans. Once you identified your problems, you can build indexes and check again. Then you should regularly check if your indexes are used.

To be able to test for multiple databases, I recommend you using Testcontainers. That's my configuration to start the container:

I don't get it either. Why not use something like https://testcontainers.com/?

Testing with added infrastructure can be quite tricky. testcontainers aims to solve this by providing an open-source framework for providing local, lightweight containers for your application that can be immediately thrown away after use. It also has a Rust SDK!

This is a good start. But DynamoDB Local is a great fit for Testcontainers which "is an open source framework for providing throwaway, lightweight instances of databases, message brokers, web browsers, or just about anything that can run in a Docker container."

Devservices supports the automatic provisioning of unconfigured third party services in development and test mode. They can be provided by extension leveraging (usually) TestContainer library.

I hadn’t heard of Test Containers[1], but it looks really useful - thanks for the rec.
