> And also is there any alternate solution for partitioning to get performance improvement and data separation.

First, let me dispel the myth that PARTITIONing will automatically give you a performance improvement. There are a limited number (about 3) of use cases for which PARTITIONing gives any perf. Please describe your dataset, and why you think partitioning might help.

Second, I question whether you really need FOREIGN KEYs in a production system. The code should be thoroughly QA'd such that the FK checks never find a problem with data integrity. Any CASCADEing can be done in code, or buried in Stored Procedures, or a "database layer" between the end-users and the server.
And... FOREIGN KEY checks are a performance hit.
