We have a file based batch system which runs for 2 hours and handles 2-3 million records. The current process uses shell scripts, sql to do this. (We transform the data, stage it and then do the updates/inserts/valuation)
Can someone tell me about the performance/volume metrics of using a EMS/ESB with java to do the above tasks? We are not sure we will be able to match the performance / volume.
Thanks, Nit
