Best Practices for Instagram-style Feeds

The blog post outlines best practices for setting up activity feeds in a simple photo-sharing application, focusing on using UUIDs for unique identification to prevent collisions. It details the use of different types of feeds: flat feeds, aggregated feeds, and notification feeds. Flat feeds like "user" and "timeline" store individual user photos and allow users to follow others, respectively. Aggregated feeds, such as "timeline_aggregated," provide daily summaries of activities using a structured format for actors, verbs, and timestamps. The notification feed tracks activities like "like" or "follow" to inform users about interactions with their photos. The post also emphasizes storing activity IDs in the database to manage actions such as unfollowing or unliking. Future posts will explore backend service implementation in Go and an Android example application demonstrating these practices.
