Subject [jira] Commented: (SOLR-792) Pivot (ie: Decision Tree) Faceting Component
Date Tue, 19 Oct 2010 21:09:29 GMT


Hoss Man commented on SOLR-792:

If we keep it as a separate component, then it puts an additional burden on people to remember
to configure it, and figure out where to put it - before or after the "normal" facet component.
And if we add it as a default component that is always there, then stuff like debugging output,
etc, will list this separate component.

I'm not sure I see a benefit to this being a "user visible" component.

As far as i'm concerned, all of the things you listed are valuable reasons why this *should*
be a user visible component -- they are also reasons why i think we should try to refactor
the existing FacetComponent into separate components:

* Ability to discreetly enable/disable them by removing them from the "components" list (ie:
maybe you need facet.query and facet.range but you don't want facet.field and facet.pivot
to be available because of the performance impacts)
* ability to see distinct timing data from each of them independently

..refactoring the existing component should be a separate Jira, but since this work was already
done to keep the pivot code isolated, combining it now seems like a bad idea (unless i'm the
only person who things these should *all* be distinct, user visible, components)
