title: #TigerGraph Import : one csv for each relation type?
body: <p>I’ve just started using TigerGraph, and I saw in the import example that the edges files: friendship.csv is separated from the vertices files: person.csv.</p>
  <p>Does it mean that if I have, say, 10 edges types I need or it would be better, to have 10 distinct csv files, each for a specific edge type ?</p>
