方法详细资料

instance

public static org.apache.calcite.jdbc.CalcitePrepare.SparkHandler instance()

Creates a SparkHandlerImpl, initializing on first call. Calcite-core calls this via reflection.

flattenTypes

public org.apache.calcite.rel.RelNode flattenTypes(org.apache.calcite.plan.RelOptPlanner planner,
                                                   org.apache.calcite.rel.RelNode rootRel,
                                                   boolean restructure)
