Issue/Introduction

Memory and time constraints are major considerations when processing a Copybook with several records.

Environment

All supported DevTest versions and environments

Cause

N/A

Resolution

A binary file is processed using a copybook mapping file with multiple records. 

Lets say you need to save 200 values from each record to be processed later.

Using a test file with 2,000 records, it is determined it takes about 2 seconds to process and save the values from each record to variables using Filters.

However, the final version will contain 100,000 records.

Therefore,  100000 records * 2 seconds = 200000 seconds or 200000/60/60 = 55.5 hours. 

Most likely this amount of time is unacceptable.

In this case DevTest may not be the best tool for this scenario.
