To understand how fast Phoenix is when compared to Rails, I created a simple application to benchmark both frameworks. The results are quite interesting.

Preload is a part of Ecto.Query module that provides the Query DSL. Preload is a powerful tool that allows you to avoid N+1 queries from negatively affecting our performance. We must explicitly preload the data that we are accessing for an association between data. However, it’s easy to make mistakes when using preload. During the article, I will try to answer questions about making a decision on how to use preload.

Announcing Oban, an Ecto/PostgreSQL based job processing library with a focus on reliability and historical observability.

Oban’s primary goals are reliability , consistency and observability. It is fundamentally different from other background job processing tools because it retains job data for historic metrics and inspection.

Version 0.2.0 was released today!

Python is the de facto language for machine learning and data science. There are numerous libraries and frameworks available in Python for this purpose. Elixir on the other hand is relatively new and doing machine learning in Elixir is still not easy. In this article, I will present how we can use a machine learning model trained using Python from a Phoenix (Elixir) web application. Since the process remains the same, it does not necessarily have to be web application. Any Elixir application can use similar approach and use pre-trained Python ML models.
