Server side processing with rest service json format on page loading?

dharm

Dear data table,
I am really fascinating about dataTable. It's really awesome.
My question basically is I have lot of data like in 5 millions for dataTable. It took More of 20 min through network to pass with http protocol of rest service.Then after data table renders data quickly. Page loading taking lot of time. I need to make call rest service on every page .like 10 records on first page by default then 10 next record for next page likewise. Could you please let me know how can I do server side json manipulate and populate on page data on data table. Or we can save other columns in cache. please let me know any alternative way of doing on page with Ajax call of rest service in json format.

Thanks in anticipation.
