Project mention: Using IRIS and Presto for high-performance and scalable SQL queries | dev.to | 2025-01-19
The rise of Big Data projects, real-time self-service analytics, online query services, and social networks, among others, have enabled scenarios for massive and high-performance data queries. In response to this challenge, MPP (massively parallel processing database) technology was created, and it quickly established itself. Among the open-source MPP options, Presto (https://prestodb.io/) is the best-known option. It originated in Facebook and was utilized for data analytics, but later became open-sourced. However, since Teradata has joined the Presto community, it offers support now.

When I manage a project and have the freedom to choose my configuration structure, then I always use typescript. I never understood the desire to have configuration be in ini/json/jsonnet/yaml. A strongly typed configuration with code completion seems so much more robust. Except of course your usecase is to load or change the config via an API.
I like what apple is doing with https://pkl-lang.org/ though.
