Kafka Connect (or Connect API) is a framework to import/export data from/to other systems. It was added in the Kafka 0.9.0.0 release and uses the Producer and Consumer API internally. The Connect framework itself executes so-called "connectors" that implement the actual logic to read/write data from other systems.
The pub/sub pattern scales well for small networks with a small number of publisher and subscriber nodes and low message volume. However, as the number of nodes and messages grows, the likelihood of instabilities increases, limiting the maximum scalability of a pub/sub network. Example throughput instabilities at large scales include:
In computing, the producer-consumer problem (also known as the bounded-buffer problem) is a family of problems described by Edsger W. Dijkstra since 1965.. Dijkstra found the solution for the producer-consumer problem as he worked as a consultant for the Electrologica X1 and X8 computers: "The first use of producer-consumer was partly software, partly hardware: The component taking care of the ...
Further, (4) a common variant of the producer-consumer problem is to allow *multiple* producers and consumers, in which case an additional mutex is necessary in order to get mutual exclusion, but (5) the order in which producers / consumers wait and signal the mutex and semaphores may lead to deadlock if implemented incorrectly.
AMQP is a binary application layer protocol, designed to efficiently support a wide variety of messaging applications and communication patterns. It provides flow controlled, [3] message-oriented communication with message-delivery guarantees such as at-most-once (where each message is delivered once or never), at-least-once (where each message is certain to be delivered, but may do so ...
Sequence diagram for depicting the Message Broker pattern. A message broker (also known as an integration broker or interface engine [1]) is an intermediary computer program module that translates a message from the formal messaging protocol of the sender to the formal messaging protocol of the receiver.

The producer can simultaneously reach the consumer through a direct market, such as a website, or sell to another company or retailer that will reach the consumer through another channel, i.e., a store. An example of this type of channel would be franchising. [4] The role of marketing channels in marketing strategies Links producers to buyers.
