Vert.x JDBC client mutiny binding and result sets

[guykatz]

Hi all
I have 2 external data sources my service needs to call to get raw database data.
I intend to use vert.x JDBC client mutiny binding and combine the 2 uni responses in order to then 'work' on the combined result.
The thing is that once the unis are combined I have a tuple with the 2 result sets and once I want to operate on them or they're JSON array representation, I am already out of the scope of mutiny.
I can stream with java streams the JSON array.
So I think what I am asking is:
Should I create a mutiny object to wrap the results I wish to operate upon? Or staying with java streams is enough?
How do I make the decision?
Thanks for the help.

In general, databases do not stream. It's especially true when using JDBC. So, the row sets are already in memory. Use java.util.stream is good for that use case.
