Uwe Schindler updated SOLR-7753:
--------------------------------
Fix Version/s: (was: 5.4)
5.5
> Parse localParams and query object once and re-use when hanging queries under
> pivots
> ------------------------------------------------------------------------------------
>
> Key: SOLR-7753
> URL: https://issues.apache.org/jira/browse/SOLR-7753
> Project: Solr
> Issue Type: Improvement
> Components: faceting
> Reporter: Shalin Shekhar Mangar
> Labels: difficulty-easy, impact-medium
> Fix For: 5.5, Trunk
>
>
> When hanging facet.query under pivots, the query (and localparams) is parsed
> for every pivot value. We can avoid it by parsing and caching the query
> object just once during FacetComponent#prepare.
> As noted by Hoss in SOLR-4212:
> {quote}
> It's not just an issue of localparams, but also the parsing & construction of
> the Query object – doing that once per request (just like the way you've
> changed the range faceting to do all the bucket calculation once) could give
> us some serious performance savings when facet.query params are hung of of
> many and/or large pivot trees. (should just mean a pretty trivial new
> subclass of FacetBase that also has a public Query getQuery() accessor)
