@liancheng @chenghao-intel I think we can did it like mysql's range
optimizer:http://dev.mysql.com/doc/refman/5.7/en/range-optimization.html. I
have implemented it in my
branch:https://github.com/lianhuiwang/spark/tree/partition_pruning. I did not
combine many ranges because it will transform partition pruning predicates to
Hive's filter expression in getPartitionsByFilter() and Hive's metastore
database can filter partitions.
