Hi Vikas!
You are not required to leverage RIH when publishing change events to downstream applications or cloud storage. However, you will want to leverage some integration platform to read the events off of the the queue that Reltio will push the events onto. Reltio will publish events onto an AWS SQS, Google Pub-Sub or Azure Service Bus to be subscribed to. Reltio Integration Hub is an option to use for this in addition to other integration platforms.
Thanks!
