Spring Batch Query

[An Sush]

Hi,
I am new to spring batch framework. I have to implement batch in my application so as to download records to a flat file in case search results are more than 5000. The restrictions are I have to avoid making any db changes as datamodel is freezed. I was going through the spring batch documentation and found that few metadata tables like Batch_Job_Execution, Batch_Job_Instance, Batch_Job_Params and Batch_Step_Execution are mandatory.
Cant I get rid of these tables and still implement batch? Kindly reply soon
Thanks,
An
