Description
The plist Streaming Expression wraps any number of streaming expressions and opens them in parallel. The results of each of the streams are 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:
plist(tuple(facet1=facet(...)), tuple(facet2=facet(...)), tuple(facet3=facet(...)))
