Subject hive partitions

Hi,

Just yesterday I saw the PARTITION feature and runned a test partitioning by
day and the results are very good. So I'm wondering if I can create a table
with 5 or 6 fields as partitioner and use this instead of running group by
regular fields.

The performance will slow down? Which is the best GB space for each
partition?

Thanks in advance,
Raimon Bosch.
