public class SortConvertPrule
extends org.apache.calcite.rel.convert.ConverterRule

Rule that converts an Sort to a physical SortPrel, implemented by a Drill "order" operation. The Sort is added in optiq's AbstractConvert call, when it enforces certain "order" to the input stream. Drill uses this rule to convert such sort enforcer into physical SortPrel.
