MaxScanStrategy

case class MaxScanStrategy(session: SparkSession) extends Strategy with SQLConfHelper with PruneFileSourcePartitionHelper with Product with Serializable

Add MaxScanStrategy to avoid scan excessive partitions or files 1. Check if scan exceed maxPartition of partitioned table 2. Check if scan exceed maxFileSize (calculated by hive table and partition statistics) This Strategy Add Planner Strategy after LogicalOptimizer
