Hi Gerard,
Thanks for your answer.
Just to make sure I understood it correctly.
If two consumers are running , one with group.id : “purchase_order_metrics”
and another group.id : “purchase_order_communication” both both consumers
doing consumer.subscribe("purchase_order_updated”) both will always receive all
the messages that will come after the moment in which each consumer is up and
running , without any specific configuration needed ?
Thanks

Hi, if you use a new group for a consumer, the auto.offset.reset value will
determine whether it will start at the beginning (with value earliest) or
at the end (with value latest). For each group a separate offset is used,
to two consumer, belonging to two different groups, when started before the
producer, will both consume each message produced.
