Changefeeds are for getting updates to the results of queries on the database. So for example, getting the top 5 users ordered by their score. The app leaves a connection open to the database, and the database pushes changes to the query results whenever they happen. The app can then also have a persistent websocket connection or whatever to the client, so you're able to get push architecture all the way from the data source to the client. |
