Re: Key Partition Performance Measurement
It is usually not useful to partition on the first field in the PRIMARY KEY.
If "select * from UserUsage where Msisdn=<number> order by Date desc limit 7" is your primary query, then a non-partitioned table with
INDEX(Msisdn, Date)
is optimal. (Indeed, that is your PRIMARY KEY).
