Module 2: message visible in kafkacat only after some time

[gunnarmorling]

Reported twice now; the call to kafkacat returns an error for some time after the message has been sent:

kafkacat -C -b production-ready-kafka-bootstrap -t OrderEvents -o beginning -f 'offset: %o, key: %k, value: %s\n'

% Auto-selecting Consumer mode (use -P or -C to override) % ERROR: Failed to query metadata for topic OrderEvents: Local: Broker transport failure

@ppatierno, would that happen to ring a bell for you?

The HTTP request to the order service successfully returns, i.e. the message must have been sent successfully (and a record must have been persisted in the DB). But only some time after that, the kafkacat command returns the message.
