Note that delete_column_statistics is needed to remove the entries from the meta-store when a table is dropped. Also note that currently Hive doesn’t support drop column.

Note that in V1 of the project, we will support only scalar statistics. Furthermore, we will support only static partitions i.e., the both the partition key and partition value should be specified in the analyze command. In a following version, we will add support for height balanced histograms as well as support for dynamic partitions in the analyze command for column level statistics.
