Is the PRIMARY KEY a simple integer?

PARTITION has a chance of shining if the partition key is _not_ the first part of the PRIMARY KEY. Such as
PRIMARY KEY(a,b) and partition on b.
It does help if the WHERE clause talks about both a and b.

Was "# Queries with IN parameter values from 100 to 2000 were performing extremely well than a regular table" then only beneficial situation? Did all the IN values hit the same partition?

How many partitions did you have?
