Introduction to PubNub Data Storage and Playback

Data Storage and PlaybackPubNub Data Storage and Playback (sometimes called ‘history’) allows you to store realtime message streams for future retrieval and playback. Data Storage and Playback populates chat, collaboration, and machine configuration on app load, stores message streams with realtime data management, retrieves historical data streams, then replays live events during rebroadcasting.

Storage and Playback is made up of three features:

  1. Storage: stores realtime data for any length of time
  2. History: retrieves messages across a specified time period
  3. Replay: publishes all messages in the order and time originally sent
