LogicalQueryStageStrategy

object LogicalQueryStageStrategy extends Strategy with PredicateHelper

Strategy for plans containing LogicalQueryStage nodes: 1. Transforms LogicalQueryStage to its corresponding physical plan that is either being executed or has already completed execution. 2. Transforms Join which has one child relation already planned and executed as a BroadcastQueryStageExec. This is to prevent reversing a broadcast stage into a shuffle stage in case of the larger join child relation finishes before the smaller relation. Note that this rule needs to applied before regular join strategies.
