Thank you for your valuable responses. Apparently, we cant increase multi subdoc count. As David suggests I preferred making 2 couchbase calls asynchronously. Except these, I have last another question. When making normal kv operations in case of any failover we can use getAnyFromReplica but I couldn’t found an API to do it for sub-document operations. Am I missing something? Or does sub doc api performs internally what I described?
