What is the difference between Logica and Mangle?

Hi,

There is another programming language called Mangle released by Google recently and Logica is mentioned in the README.

If translating non-recursive Datalog into SQL queries sounds interesting, you should check out the Logica open source project.

What is the difference between Mangle and Logica?

Hi,

Thanks again for the question!

It’s hard to make a direct comparison between tools without a standardized evaluation process (e.g., benchmarking). That said, my (possibly wrong) understanding is that the key difference is that Mangle is written from scratch, whereas Logica compiles scripts into SQL - using Python as a glue layer to enable recursion.

Our focus with Logica is to make it a versatile programming language: on one hand, it can handle hard reasoning problems, similar to those addressed by traditional logic programming approaches. On the other hand, we emphasize scalability, enabling Logica to efficiently process large datasets - something many logic programming languages were not originally designed for - by leveraging underneath database engines like DuckDB and BigQuery.

I hope this helps answer your question! For more details, please check this paper Logica: Declarative Data Science for Mere Mortals
