public class SetOptionHandler
extends AbstractSqlHandler

Converts a SqlNode representing: "ALTER .. SET option = value" or "ALTER ... SET option" statement to a PhysicalPlan. See DrillSqlSetOption

These statements have side effects i.e. the options within the system context or the session context are modified. The resulting DirectPlan returns to the client a string that is the name of the option that was updated or a value of the property
