I remember reading articles about how 3G connectivity was going to transform performance and, more generally, the way we used the internet altogether. I remember how, later on, a common question I would get in after giving performance-focused presentations was: “Is any of this going to matter when 4G is available?”

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. This separation allows us to tune system configuration and scaling policies independently for different event priorities and traffic patterns.
