Matthew Ezell created an issue   Hiera / HI-471 Allow backends to perform Qualified Key Lookup Issue Type: New Feature Assignee: Unassigned Created: 2015/09/23 10:05 AM Priority: Normal Reporter: Matthew Ezell Since HI-14 , Hiera can lookup leaf elements from structured data. This was implemented by splitting the lookup key into period-separated values and calling into the backends for the the first token only. Hiera then pulls out the requested value from the data returned from the backend. For certain backends with deeply structured data, the first token may contain a substantial amount of data that is non-trivial to return. Imagine, for example, a LDAP backend that can return data about users and groups on the system: hiera users.user123.shell would have to return the entire users hash, which could contain thousands of superfluous records when we only want a string. Passing the entire key to the backend and letting it intelligently handle what data to retrieve could be a huge optimization. The difficulty in implementation is how the backend can tell Hiera that it supports Qualified Key Lookups so that Hiera doesn't try to do it itself.
