    Hi Avnish,

    External objects are similar to custom objects, except that they map to data that’s stored outside your Salesforce org. ach external object relies on an external data source definition to connect with the external system’s data.External objects enable your users and the Lightning Platform to search and interact with the external data.

    Platform events are part of Salesforce’s enterprise messaging platform. The platform provides an event-driven messaging architecture to enable apps to communicate inside and outside of Salesforce. Before diving into platform events, take a look at what an event-based software system is.You can use platform events to deliver secure and scalable custom notifications within Salesforce or from external sources.

    Big objects provide consistent performance for a billion records or more, and are accessible with a standard set of APIs to your org or external system.It allows you to store and manage a massive amount of data on the Salesforce platform.

    Hi Avnish,

    Big objects let you store and manage massive amounts of data on the Salesforce platform. Big objects capture data for use within Lightning Platform and are accessible via a standard set of APIs to clients and external systems. What differentiates big objects is that they have been built to provide consistent performance whether there is 1 million records, 100 million, or even 1 billion records. This scale is what gives big objects their power and what defines the features that are provided.

    Platform events are your custom platform event determines the event data that the Lightning platform can produce or consume. Platform events are part of the Salesforce enterprise messaging platform. The platform provides an event-driven messaging architecture to enable apps to communicate inside and outside of Salesforce.

    External objects are similar to custom objects, except that they map to data that’s stored outside your Salesforce org. Each external object relies on an external data source definition to connect with the external system’s data.

     

    Thanks.

    Hi,

    External objects are similar to custom objects, except that they map to data that's stored outside your Salesforce org. Each external object relies on an externaldata source definition to connect with the external system's data.

    Big Objects. Big objects let you store and manage massive amounts of data on the Salesforce platform. ... Big objects capture data for use within Lightning Platform and are accessible via a standard set of APIs to clients and external systems.

    Platform events are based on a publish-subscribe architecture. Apps can publish platform events byusing Apex or one of the Salesforce platform APIs (SOAP, REST, or Bulk API). ... Apps can subscribe toevents through Apex triggers or CometD clients. CometD is a scalable HTTP-based event-routing bus.

    Hope this helps.
