Hey @Martin_Chavez!
It looks like a similar question was asked several years ago: Technical description of the current Couchbase protocol?
However, I’m not sure how up-to-date this information is. You can learn more about managing connections with the latest Java SDK on the docs site.
I’ll let someone else correct me if more up-to-date protocol information is available, but I hope this helps for the time being! Feel free to follow up if needed.
Cheers
