Hi Naidu,
I believe you are looking for Caching and Asynchronous capabilities.
You can use Data store for Caching capabilities - Developer - webMethods.io Integration
wMIO.integration does have asynchronous capabilities. wMIO also can work with external messaging systems - e.g., AMQP, MQTT, SQS, Google Pub Sub, etc.
We plan to offer Messaging capabilities in built in future releases.
