I'm trying to understand how the partition key works and whether I need to specify a partition key for my topics or not. What happens if I don't specify a PK and I have more than one consumer that wants all messages in a topic for a certain period of time? Will those consumers get all the messages, but they just may not be ordered correctly?
The current scenario is that we will have events going into a topic based on customer and the data will remain in the topic for 24 hours. We will then have multiple consumers reading messages from that topic. They will want to be able to get them out over a time range (could be last hour, last 8 hours etc). So if I specify the same PK for each subscriber, then each consumer will get all messages in the correct order? If I don't specify the PK or use a random one, will each consumer still get all the messages but they just won't be ordered correctly?
