Streaming events are instant notification messages that one system (the publisher) sends to another (the subscriber). With push technology, the publisher pushes data to the subscriber. This is the opposite of pull technology. With pull technology, clients request data from the server periodically.
When to Use Change Data Capture
Say you have an enterprise resource planning (ERP) system that stores your business information, and some of your data in Salesforce is duplicated there. To ensure that your ERP data is up to date, you can use change events to synchronize changes to the Salesforce records in your ERP system.
An Example Integration App
Robert Bullard is a software developer at Get Cloudy Consulting, a high-tech consulting firm specializing in CRM implementations. Robert is developing an HR synchronization app for a client. The app synchronizes Salesforce record data changes with an HR system that’s external to Salesforce.
Data Synchronization with Change Data Capture
