Example: for a table having partition keys country and state, one could construct the following filter:
country = "USA" AND (state = "CA" OR state = "AZ")
In particular notice that it is possible to nest sub-expressions within parentheses.
The following operators are supported when constructing filters for partition columns (derived from HIVE-1862):
=<<=>>=<>ANDORLIKE(on keys of typestringonly, supports literal string template with '.*'wildcard)
