ResourceProvider
resources
based on the given request and predicate
information.
Note that it is not required for this resource provider to completely filter
the set of resources based on the given predicate. It may not be possible
since some of the properties involved may be provided by another
provider
. This partial filtering is allowed because
the predicate will always be applied by the calling cluster controller. The
predicate is made available at this level so that some pre-filtering can be done
as an optimization.
A simple implementation of a resource provider may choose to just return all of
the resources of a given type and allow the calling cluster controller to filter
based on the predicate.request
