A route is how data moves from A to Z. But, it's a higher level concept than something like a "queue." A route is like Dorothy meeting characters on the Yellow Brick Road. The queue is the road. Dorothy is the data payload, and in K3 that data meets a lot of interesting characters (components) along the way which affect the payload. One note is that the route is not always linear, it is actually data flow graph which is an orchestration of data meeting components among topics. Drawing from the distributed architecture a series of routes in K3 often looks like this image.
The K3 Core
K3 is built on an entirely distributed architecture. We designed it to give customers the power of user driven data management, horizontal scalability of data streams, and the ability to replay historical data on demand.
