OMRS Event Topic

The OMRS Topic is an event topic, typically hosted by Apache Kafka, that an open metadata repository cohort uses to synchronize metadata between metadata repositories. It is accessed by the Open Metadata Repository Services (OMRS) components through the OMRS Topic Connector. The OMRS Topic Connector is a pluggable OCF Connector that allows the use of different messaging infrastructures to support the OMRS Topic without affecting the implementation of the OMRS.

OMRS Topic Events

The OMRS Topic is used to send and receive OMRS Events. There are three types of OMRS events that are sent/received on the OMRS Topic:

TypeDef events and Instance events are collectively called Repository events because they affect the contents of the open metadata repositories. Details of the structure of the different types of OMRS Events can be found on the events descriptions.

Enterprise OMRS Event Topic

The enterprise repository services combine the OMRS events from all of the open metadata repository cohorts that the server is connected to and makes them available to each local Open Metadata Access Service (OMAS). This is called the enterprise OMRS event topic. By default, it is implemented as an in-memory open metadata topic.
