Ably Introduces Subscription Filters Feature

Ably has launched a new feature called 'Subscription Filters' allowing personalized realtime data streams for subscribers using a single channel.

This feature enables cost savings and simplifies channel architecture by allowing clients to receive only a portion of data they are interested in.

Common use cases include filtering in large chat rooms, updating active dashboard views, and limiting client access to specific data criteria like sports or financial data updates.

Subscription Filters is currently in preview, meaning it will be refined based on user feedback, but no dramatic changes are expected.

A demonstration showcased use in stock inventory management, where regional managers receive updates filtered by location and product attributes.
