When i use the filterpushdown , i found the FilterPushDown only take effects in orc/parquet/testFilter  when using *flink planner.*

Because the call  applyPredicate(List<Expression> predicates) predicates 

1) *PlannerExpressin* flink planner the PushFilterIntoTableSourceScanRule  RexProgramExtractor.visitCall return PlannerExpression

2) *CallExpression*  blink planner , *can not match current And Or EqualTo and so on*, which it PlannerExpresion  the PushFilterIntoTableSourceScanRule  RexNodeExtractor.visitCall return ResolvedExpression
