title: Combination of postgresql and neo4j for networking site
body: <p>We are designing a networking site where data would be connected to each other in complex way. 
  We plan to use Neo4j so that we could escape costly join otherwise required. Since neo4j is specifically designed for graph like data so it seems suitable.</p>
  
  <p>however we have realized that although neo4j is fast in some aspect but the representation of Relational data is best done through relational database. So its like we plan to use neo4j at some of the functionality and postgresql at other functionality. </p>
  
  <p>For example-- We would use neo4j for finding relevant feeds to user by searching through different nodes which he follows. While for other activities like updating profile information etc we would like to use postgresql. We did some performance testing for profile information updation and found that postgresql is faster than neo4j. While analyzing feed data, neo4j is much much faster.</p>
  
  <p>Now my question is have anyone used combination of databases like this before. Specifically neo4j with postgresql. We do find some problems while integrating different databases but we find it worth it.</p>
  
  <p>Please share your experience and feedback. Thanks</p>
