xDB does not support views. Having said that, however, most performance problems with joins can, in our experience, typically be addressed by a combination of one or more of:

  • optimizing/rewriting the queries (narrowing down the result set early; basing the joins on the most selective attributes; etc.)
  • using appropriate indexes
  • "denormalizing" the XML structure to eliminate (some) joins.
