US Patent 11989661 Dynamic rules for rules engines

Computer-implemented systems and methods update rules engines in a distributed computer system with new rules in a lightweight, non-intrusive, real-time manner. Rules engines are subscribed to a pub/sub service for new rules pertaining to a topic. A rules manager publishes a new rule to the pub/sub service with an associated topic. The rules engines download the new rule and store the new rule in-memory for execution without downtime.
