Subject [jira] [Created] (OAK-178) Query: index definition documentation and tooling
Date Wed, 11 Jul 2012 13:48:34 GMT
Thomas Mueller created OAK-178:

             Summary: Query: index definition documentation and tooling
                 Key: OAK-178
                 URL: https://issues.apache.org/jira/browse/OAK-178
             Project: Jackrabbit Oak
          Issue Type: Bug
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller

Unlike Jackrabbit 2.x, indexes in the Oak query engine are user defined, that means data is
only indexed if there is a matching index. Those indexes are then automatically used for the
appropriate queries. The current plan is to define indexes as nodes within a repository. An
index is created if an index metadata node is created, and the index is removed if the index
metadata node is removed. The index content is automatically updated if the content changes
(either synchronously or asynchronously).

The location and structure of the index metadata needs to be defined and documented.

Also, to simplify defining and managing indexes, it may make sense to write a utility (helper
class) for managing indexes. Internally, this utility uses the regular JCR API and accesses
the documented index metadata nodes.
