1. Is there a way to model a process, such that process instances will not keep

Thank you folks for the quick response!
A use case is such that the process has over 25 user input tasks with one of them recurring every alternate times (that user input task re occurs 12 times in the process). We thought of calling sub process for that task to improve the performance but fear that data will be lost once the sub process gets archived. Any suggestions on how to model process with tasks which are repeated multiple times throughout the process?
