title: CouchDB data syncing/downloading
body: <p>I’m building a new mobile application and intend to use Apache CouchDB and Couchbase Lite to implement an offline/online data syncing model. A basic CRUD is completed and working.</p>
  
  <p>My question is about how much of the data is synced. Example:</p>
  
  <p>The centralized database has data of 3 users. Lets say each user creates 100Mb of data that is syncronized in the server.</p>
  
  <p>Data created by each user is unnaccesible for other users, and the queries that are made from the mobile client never include the data of other users.</p>
  
  <p><strong>If a user only queries and creates its own data, will he have in his device 300Mb of data or only his own 100Mb?</strong></p>
