An integration architect needs to build a solution that will be using the Streaming API,...

The integration architect should consider Change Data Capture Events and High Volume Platform Events for using the Streaming API with minimal data loss. Change Data Capture Events capture changes to Salesforce records and deliver them as events to subscribers. High Volume Platform Events are custom events that can be published and consumed at a large scale. Both types of events support reliable event delivery, which means that events are stored for 72 hours and can be replayed by subscribers in case of connection loss or failure. This ensures that data loss is minimized, even when the client re-connects every couple of days12
