Batch data processing  — historically known as ETL —  is extremely challenging. It’s time-consuming, brittle, and often unrewarding. Not only that, it’s hard to operate, evolve, and troubleshoot. In this post, we’ll explore how applying the functional programming paradigm to data engineering can bring a lot of clarity to the process. This post distills fragments of wisdom accumulated while working at Yahoo, Facebook, Airbnb and Lyft, with the perspective of well over a decade of data warehousing

These days, everyone talks about open-source. However, this is still not common in the Data Warehouse (DWH) field. Why is this? In my recent blog, I researched OLAP technologies, for this post I chose some open-source technologies and used them together to build a full data architecture for a Data Warehouse system. I went with Apache Druid for data storage, Apache Superset for querying and Apache Airflow as a task orchestrator.

Summary The information about how data is acquired and processed is often as important as the data itself. For this reason metadata management systems are built to track the journey of your business data to aid in analysis, presentation, and compliance. These systems are frequently cumbersome and difficult to maintain, so Octopai was founded to alleviate that burden.

Making slow queries fast using composite indexes in MySQL This post expects some basic knowledge of SQL. Examples were made using MySQL 5.7.18 and run on my mid 2014 Macbook Pro. Query execution times are based on multiple executions so index caching can kick in. The use-case came from a real application and the solution is used in production. So you have inserted preliminary data to your database and run a simple COUNT(*) query against it with a simple WHERE clause and… the spinner is still run
