Inbound Channel Pattern for Efficient 1-1 Chat Management

PubNub's new Chat Resource Center provides resources for building and deploying mobile and web chat, and introduces strategies for efficiently managing message retrieval in scenarios with numerous chat channels. Traditional 1-1 chat setups, which require separate channels for each user pair, can become inefficient with many friends, leading to a high volume of history() calls for missed messages. To optimize, the introduction of an Inbound channel for each user allows all incoming messages, regardless of the sender, to be centralized in one channel, much like an email inbox, thereby reducing the number of history calls needed. Additionally, for group chats, large groups can still utilize separate channels to maintain efficiency. A Hybrid pattern, combining Inbound and unique Hybrid channels for each pair of users, enables easier retrieval of chat history, allowing users to access messages from all chats via the Inbound channel while having the option to view specific conversations through the Hybrid channel. This dual-publishing method enhances the ability to manage both new messages and historical conversations effectively.
