I have an app that should split one day to micro-services each micro-service (right now inside the app) is init it’s own couchbase client (currently same bucket and cluster). Can it cause issues?
I’m not fully sure I understand the question, but there is no problem having multiple CouchbaseBucket instances to the same bucket in the same cluster. It’s not the most efficient way to do things, but it won’t harm anything.
Definitely do not create a new bucket instance each time. You should reuse them.
