Platform takes into account preferences for communication channels of registered users when sending messages

Sending messages should not block the flow of business process execution and should be performed asynchronously

Platform provides scaling and load control capabilities at the level of individual communication channels

To implement the interface of asynchronous interaction with the message sending subsystem, an approach using Kafka as a message broker was chosen, which provides guarantees of delivery and Exactly-Once message processing semantics
