Correlating Asynchronous Requests

Hi,
I have a situation where many requests and responses are sent over Logstash and I have to correlate each pair request/response.
I don't know when neither wheather the response is coming, but when and if it comes I'm able to correlate them with an ID which I can use as a Join field.

My question is:

Is the Elasticsearch join datatype the best way to do this?

But the doc says:

The only case where the join field makes sense is if your data contains a one-to-many relationship where one entity significantly outnumbers the other entity.

Which is not my case because I going to have millions of one-to-zero_or_one relationship.

If not, is there better ways?

Thanks,
