text: What role is Set playing. NS will decide how data is stored and so on. For each NS, there will be 4k physical partitions. And what is Set playing here? Does Set have any impact on the physical storage? If I use a statement to scan a set as follow:
  Statement stmt = new Statement(); stmt.setNamespace("persistusers30d"); stmt.setSetName("users"); RecordSet rs = client.query(null, stmt);
  Will it go though the whole namespace?
  And also I noticed that a key returned from aerospike scan using
  Key key = rs.getKey(); has the set name in its toString method. Since record key is just a digit, where is Set name stored?
  This Set thing is confusing me a lot
