The old way: fetch and pray
In the current paradigm, getting data means making a request. Your application calls an API endpoint. The server responds with a snapshot of the data at that moment. Then you poll again to check for changes. Then you handle rate limits, caching, stale data, and synchronization conflicts.
This model is fundamentally pull-based. The consumer is responsible for knowing when data has changed. The server is passive — it waits to be asked. Every request is a bet that the response will still be valid by the time you process it. The more real-time the data, the more frequently you have to poll. The more you poll, the more load you create. The entire edifice of webhooks, WebSockets, server-sent events, and change data capture exists because the base model — request-response — is wrong for a world where data changes continuously.
Subscriptions reverse this. The consumer subscribes once. The publisher pushes changes as they happen. The consumer doesn't poll. The consumer doesn't refresh. The data is always current because the subscription is a live connection.
Concrete example: banking
Today: You log into your bank's website. The server queries its database and renders a page with your recent transactions. You see a snapshot. If a transaction happens while you're looking, you won't see it until you refresh. To get your data into another tool, you download a CSV — a copy that will be stale within minutes.
With Inflect OS: Your bank publishes a transaction stream. Your selfspace subscribes. The transactions appear in your financial view as live data — not a screenshot, not a CSV, but structured records you can query, filter, and combine with other streams. When a new transaction posts, it appears instantly. You never refresh. You never download. You subscribed.
