> Currently to drop the matching partitions, Spark will first get all matching Partition objects from Hive metastore, and just use the partition values of these Partition objects.
> We can get the matching partition names instead of the partition objects for the following reasons:
> 1. we can also get partition values through a partition name (like a=1/b=2)
> 2. the byte size of partition name is much smaller than partition object, which will help improve the performance of drop partitions.
