Subject [jira] [Commented] (SOLR-9467) Document Transformer to Remove Fields
Date Wed, 07 Sep 2016 03:33:20 GMT


Alexandre Rafalovitch commented on SOLR-9467:

How is this going to affect LazyFieldLoading? Since this is for performance purposes, will
that field still be loaded and then ignored? Or will it not load at all?

> Given that SOLR-3191 has become bogged down and inactive, evidently stuck in low level
details, and since I have wished several times for some way to just get that one big field
out of my results to improve transfer times without making a big brittle list of all my other
fields. I'd like to propose a DocumentTransformer that accomplishes this.
> It would look something like this:
> {code}&fl=*,[fl.rm v="title"]{code} 
> Since removing one field with a known name is probably the most common case I'd like
to start by keeping this simple, and if further features like globs or lists of fields are
desired, subsequent Jira tickets can be opened to add them. Not attached to specifics here,
only looking to keep things simple and solve the key use case. If you don't like fl.rm as
a name for a transformer, suggest a better one (for example).
