How to transfer bulk data from one entity to multiple?

Hi mendix forum!   I am a bit new to mendix, so i have some trouble while synchronize the data. Let me explain. In my case am having one entity called IMS in that am importing 10lakhs data through excel. After importing i just copying the data to multiple entity using OQL retrive. In local its working but in AWS its throwing error that server not responding. So i changed to batch wise creating like 10k data wise. But the same issue is happen. I need a suggestion for huge data transfer

HI Sivagar,



There is copy attribute in java action, can you give it a try it will increase the performance 
if you still have the performance issue, you should work on increasing the ram size of aws
