Hello guys Maybe this question was already answered, but I cannot find it and want some more input on this topic.
I have some messages that don't have any particular key candidate, except the ID, but I don't want to use it because the idea is to group multiple IDs in the same batch. This is my use case: I have an endpoint where I'm gonna send the message ID, this endpoint is gonna return me certain information which I will use to enrich my message. In order to avoid fetching the endpoint per message I want to batch it in 100 and send the 100 IDs in one request ( the endpoint supports it) . I was thinking on using GroupIntoBatches. - If I choose the ID as the key, my understanding is that it won't work in the way I want (because it will form batches of the same ID). - Use a constant will be a problem for parallelism, is that correct? Then my question is, what should I use as a key? Maybe something regarding the timestamp? so I can have groups of messages that arrive at a certain second? Any suggestions would be appreciated Thanks.
