Hands-On Reactive Programming with Python

Channel

The channel communication pattern involves two peers. This pattern is a bidirectional communication: two nodes communicate with each other, sending messages without a strong relationship between each message. The following figure shows how this pattern works:

Although this communication pattern can be used over all kinds of communication channel, it is mostly used in network communications.

The differences between intra-process, inter-process, and network channels are as follows:

• Intra-process channels are quite rare. These would involve recursive calls to inter-dependent functions. ...
