is it possible way to handle ordering events ? about eventeum

Hi, sorry about the late reply...I've been on vacation. If using a Kafka broadcaster, ordering can be achieved using the correlation id. All events with the same correlation id will get sent to the same Kafka partition, and if you have a single consumer group reading from that partition, then ordering will be guaranteed.

That depends on your consumer configuration, but if your consumer is single threaded, then it should process the messages in order, one after the other.

okay, sound cool, just another question about consumer, how to prevent it consumes all messages at the same time. instead one by one, example
Consumer A receive message one, do some logic -> finish then -> ready to consume message two

Does it relate to offset and commit option ?
