Abstract
Incorrect system configurations can cause disruptions in the software development lifecycle from code deployment to system reliability. The correctness of these configurations can be ensured by an on-site DevOps team or by the developers themselves. A system that finds the incorrect settings automatically could be highly beneficial.
A company's internal system called Neodora uses the Open Policy Agent top-down Datalog engine to check the correctness of repositories and code in pull requests. It gives developers a faster and easier way to discover and correct mistakes. While the current implementation fulfils its purpose, it struggles with the near real-time scale that it is subjected to, leading to high costs.
We present an industrial experience report detailing how a new implementation of Neodora eliminates this weak point by leveraging the first Futamura projection to cleverly attain large-scale rule parallelisation. Our changes to Neodora led to a potential reduction in cost of nearly fifteen times.
