Salesforce introduced Platform Events with its Summer ‘17 release (API v40). While the Anypoint Connector for Salesforce has supported Streaming API Events, the following description from Salesforce might be helpful to understand the difference between Platform Events and Streaming API Events.
Platform Events
Platform Events enable you to deliver secure, scalable, and customizable event notifications within Salesforce or through external sources. Platform Event fields are defined in Salesforce and they determine the data that you send and receive. Apps can publish and subscribe to Platform Events on the Force.com Platform using Apex or using CometD in external systems. https://goo.gl/XPw6Nc #DataIntegration #ML
