Queuing requests inside the channel requires data to be chunked into self-contained messages so that the channel knows how much data to buffer and deliver at any one time. The two systems still depend on a common data format, but we can remove this dependency by allowing for data format transformations inside the channel. If the format of one system changes, we only have to change the transformer and not the other participating systems. This is particularly useful if many applications send data to the same channel.
