Top 7 Relational Algebra Open-Source Projects

• substrait

  3 1,038 8.8 Python

  A cross platform way to express data transformation, relational algebra, standardized record expression and plans.

  

Project mention: Velox: Meta's Unified Execution Engine [pdf] | news.ycombinator.com | 2024-03-25

Python's Substrait seems like the biggest/most-used competitor-ish out there. I'd love some compare & contrast; my sense is that Substrait has a smaller ambition, and more wants to be a language for talking about execution rather than a full on execution engine. https://github.com/substrait-io/substrait

We can also see from the DataFusion discussion that they too see themselves as a bit of a Velox competitor. https://github.com/apache/arrow-datafusion/discussions/6441

If you are interested in D, Project:M36 [0] has an implementation of TutorialD that I found to be fun to play with.

• relic

  13 395 3.6 Clojure

Project mention: FoundationDB: A Distributed Key-Value Store | news.ycombinator.com | 2023-07-03

I've been tooling around with "Tuple Database", which claims to be FoundationDB for the frontend (by the original dev of Notion).

https://github.com/ccorcos/tuple-database/

I have found it conceptually similar to Relic or Datascript, but with strong preformance guarantees - something Relic considers a potential issue. It also solves the problem of using reactive queries to trigger things like popups and fullscreen requests, which must be run in the same event loop as user input.
