Bad Consumer implementation in KafkaConsumer Controller #2
Description
If you activate the 'consumer.on message' event, this never ends, you will hear the messages until eternity.
Although there is a consumer, the closure of something happens with the life cycle and the consumer's problems a little more after sending the response.
Maybe I should wait for the consumer.close callback to issue the answer.
Therefore, if the controller issues his response and after this, the listener adds a new message to the response, we will get this error.
By definition, the consumer of Kafka behaves like a service or a demon and must start as a process at the beginning of the application.
Could you explain the best practice to do this? In loopback 3 we would use 'boot' directory to add a file with this responsibility.
