> Is there any record count till which doing partitioning could be useful for the above query? Or is it that partitioning is not a good idea at all for this specific query?
I have a Rule of Thumb: Do not partition a table unless it has at least a million rows.

But, that is not what you asked. I know of 3 uses for Partitioning. Only one of them speeds up by using PARTITIONs. That case involves 2-dimensional lookups.
Partitioning does not help that particular query, regardless of how many rows it returns.
Partitioning _may_ help some other query.
