static Optional<DruidTable>	DruidRels.druidTableIfLeafRel(DruidRel<?> druidRel)	Returns the DataSource involved in a leaf query of class DruidQueryRel.
static boolean	DruidRels.isScanOrMapping(DruidRel<?> druidRel, boolean canBeJoinOrUnion)	Check if a druidRel is a simple table scan, or a projection that merely remaps columns without transforming them.
