Overview

The KnowledgeBase is a backend-agnostic way of storing and querying information that’s generated about the files via InferRules.

We provide indirect access to the information stored by the knowledge base, so that we’ll soon be able to leverage different backends (for concurrent writes, caching rule output across runs, etc).
