I am exporting big data 7000 records from res.partner to third party platform via api. I found our that after 150 records anything over close to 120 sec , odoo stop working, as it only tries to load, the whole process of exporting would take 4-5 hours. 

How can I make odoo to keep going until whole process finishes?

I am thinking two options, either allow odoo to override time limitation or perform batch processing using scheduled action, but dont know how to implement it. 

Any suggestion would be much appreciated.
