jEAP Error Handling Service

The jEAP Error Handling Service (EHS) makes sure that no Kafka message is lost when its processing fails in a business application. It consumes MessageProcessingFailedEvents published by the jEAP messaging error handler, persists the failed messages, automatically retries temporary errors, escalates permanent errors to manual tasks, and provides a UI to inspect, resend and close errors — with optional grouping of related errors and Jira issue tracking.

This repository is published as a library: every business system creates and deploys its own EHS instance depending on it.
