Event Replay in Salesforce:

Salesforce supports guaranteed delivery of events from API version 37.0 onward. It does this by storing standard event volumes for 24 hours. Events are published to the event bus. In Salesforce each event is assigned a unique id stored in the ReplayId field of the corresponding event object. It mostly refers to the position of the event in the event stream. A subscriber can retrieve missed event objects using these ReplayId values.

For further information please go through the salesforce documentation:

12. Disable the listener and create 3-4 contacts object in salesforce. Since listener is disabled, it will not receive any notification.However once you enable the listener, you will receive all the notifications in the 24 hour retention window inclusing the missed notifications because replay option has been set as ALL for the listener.
