File (huge size of data) to File with a lookup to ECC

Hi,

I have a requirement where a batch file containing 3000 records is to be picked .

For each record there are two table lookups i.e 6000 lookups to ecc for a single file.This will affect the the performance of PI .

I am thinking of a synchronous proxy scenario where we will pick file and send a identifier for each record to ECC via proxy.

Based on the identifier,  ECC can send the required data for transformation for each record in a single proxy back to PI.

Then using the initial file we received transform it using values got from ecc and send a file to target.

I dont know as of now how feasible this design would be.

Please suggest any much more feasible and simpler  design solutions.

Thanks,
