Best Data Type for Hive Date Partition

Question

we need to partition our Hive Table based on date. Date/Month/Year

is it better to use int or string for the partition types.

ex:

CREATE EXTERNAL TABLE partition (id string, event timestamp and so on)
PARTITIONED BY (year INT, month INT, day INT)

Stored as Parquet

vs

CREATE EXTERNAL TABLE partition (id string, event timestamp and so on)
PARTITIONED BY (year string, month string, day string)

Stored as Parquet

Noticed that we couldn't do queries like:

... where day > 10 with the string option

Hi,I would suggest to use INT rather than STRING.Firstly, searching based INT type is faster, and secondly, like you said, you can do numeric comparison, which will be different from the STRING type comparison.
