Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all.

Replay PushTopic Streaming Events

Salesforce stores PushTopic-based events for 24 hours and allows you to retrieve stored and new events. Subscribers can choose which events to receive by using replay options.
