> Key: SOLR-12829
> URL: https://issues.apache.org/jira/browse/SOLR-12829
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Priority: Major
>
> The *plist* Streaming Expression wraps any number of streaming expressions
> and opens them in parallel. The results of each of the streams is then
> iterated in the order they appear in the list. Since many streams perform
> heavy pushed down operations when opened, like the FacetStream, this will
> result in the parallelization of these operations. For example plist could
> wrap several facet() expressions and open them each in parallel, which would
> cause the facets to be run in parallel, on different replicas in the cluster.
> Here is sample syntax:
> {code:java}
> plist(tuple(facet1=facet(...)),
> tuple(facet2=facet(...)),
> tuple(facet3=facet(...))){code}
>
