A.HASH partitioning is useful on columns which are unique
in nature where range or list partitioning cannot be done.
All the hash partitions hold an equal number of rows
thereby improving the performance and response time of the
query if the table is queried.

List partition is used on a table if you can divide table
based on column value. Something like region wise
partioning if the table contains a column like region.The
advantage of list partitioning is that you can group and
organize unordered and unrelated sets of data in a natural
way.
