>
> The existing jdbc Streaming Expression is really designed for querying
> outside SQL engines.
> The sql expression is designed to talk directly with Solr's parallel SQL
> interface.
> This will make it much easier to intermingle SQL queries with other
> expressions and leverage the new math expressions on top of SQL result sets.
> Sample syntax:
> {code}
> sql(dbcollection, stmt="SELECT ...")
> {code}
> The dbcollection parameter is the distributed front end to the database. Like
> all parallel SQL queries the stmt can reference any collection in the Zk
> instance.
