public final class OrderLimitStrategy extends AbstractTraversalStrategy<TraversalStrategy.OptimizationStrategy> implements TraversalStrategy.OptimizationStrategy
OrderLimitStrategy
is an OLAP strategy that folds aRangeGlobalStep
into a precedingOrderGlobalStep
. This helps to eliminate traversers early in the traversal and can significantly reduce the amount of memory required by the OLAP execution engine. It's worth noting that certain steps are allowed betweenOrderGlobalStep
andRangeGlobalStep
: These steps will be ignored by theOrderLimitStrategy
and thus not affect its behavior.- Author:
