Subject Re: Solr Dynamic Field Performance
Date Sun, 14 Sep 2014 16:06:13 GMT
Dynamic fields, once they are actually _in_ a document, aren't any
different than statically defined fields. Literally, there's no place
in the search code that I know of that _ever_ has to check
whether a field was dynamically or statically defined.

AFAIK, the only additional cost would be figuring out which pattern
matched at index time, which is such a tiny portion of the cost of
indexing that I doubt you could measure it.

Best,
Erick
