com.twilio.kudu.sql.rules.KuduSortRule
Direct Known Subclasses:

public abstract class KuduSortRule extends org.apache.calcite.plan.RelOptRule
Two Sort Rules that look to push the Sort into the Kudu RPC. Rule that pushes down the sort into kudu if we are sorting by columns that are a prefix of the primary key columns in the table. This rule eliminates sorting on the client.
