In this blog post, we will give an overview of the Rapid Event Notification System at Netflix and share some of the learnings we gained along the way. We thus assigned a priority to each use case and sharded event traffic by routing to priority-specific queues and the corresponding event processing clusters.

Most applications communicate with databases to, for example, pull a catalog entry or submit a new record when an order is placed. To achieve this, there must be a healthy connection between the application and the database. Application servers use connection pools to maintain connections with the databases that they communicate with.
