How to handle the huge data(>crores) in sapui5 oTable?

Hi,

I am using sap ui5 oTable for showing the huge data from hana db.While loading the huge data, the browser is going to crash.so I am fetching 100 records from db and showing the 20 records per page.so we can have 5 pagination(5*20=100)  with one manual next button.If i click next manual button , i should get next 100 records and pagination should be 6,7,8,9,10.but i could not change the pagination no.

1. how to change the default pagination number in oTable?

2.How to achieve lazy loading concept in oTable?

3.Normally how to achieve the huge data handling in oTable?

Thanks for your support.
