title: Maximum concurrent operations on couchbase single bucket
body: <p>I’m building a server for customers where each customer need to have each access to a database for serving his/her clients.
  So my thought was to assign each customer to a specific bucket but just to find out now that a single couchbase only serve maximum of 10 buckets as recommended. But now, i don’t know if sharing a single bucket across my customers using their ID combining with the collection documents name they are creating as namespace in document type will affect the performance of all customers due to heavy operation by each customer clients on a single bucket.
  I will also appreciate any database platform that can also handle this kind of project at large that performance of one customer will affect others.</p>
