Hi Palanivelrajan P,
You can consider different display options. If you stick to the List View, you can configure the number of records loaded when opening the page by setting 'Page size' (visible when editable set to False). Make sure you're not using a datasource microflow, but XPath or Database, otherwise the DS-microflow will still retrieve everything.
If you choose other views, like data grid (2), you can also setup paging.
Good luck!
Johan
