JS Generic Event Processor
Overview
The Unified Assurance JavaScript Generic Event Processor microservice is part of the microservice event pipeline. The microservice is responsible for enrichment/processing of custom JavaScript rules-based events and for forwarding them down the event pipeline to a selected target (preferably an event-sink).
Prerequisites
-
A microservices cluster must be setup. Refer to Microservice Cluster Setup.
-
Apache Pulsar must be installed. Refer to Apache Pulsar microservice.
