1. Re: How does hierarchical models work in teiid?
shawkins May 26, 2015 7:51 AM (in response to capoorhimanshu)For hierarchical sources the hierarchy will be converted to a relational model using keys to express the relationships - see our sources such as JPA, MongoDB, or Salesforce, etc. There can be a performance hits for this as the translators generally make simplify assumptions, such as only supporting source queries with a single join, to make mapping general SQL queries back to the hierarchical structure possible.
