Hi ghini,

I have just answered your support ticket on the matter, for convenience I am copying my answer here as well:

The automatic partial loading and filtering of the data are not implemented In RadMap but you can achieve it with some custom. Nevertheless, with a custom implementation, it seems possible to achieve.

Keep in mind that the RadMap is actually just a server-side wrapper of the Kendo UI Map widget and the RadClientDataSource is a wrapper of the Kendo UI DataSource widget. With that said, from the server controls' client-side object, you can access their internally used Kendo UI widget and then make use of the Kendo UI APIDocumentation and resources.

Here are also some resources that might be helpful to implement the load on demand functionality: 

You can also consider using the Kendo Map directly as it allows you some more flexibility in the way markers are loaded and you can use a sort of load-on-demand mechanism as shown here: https://docs.telerik.com/kendo-ui/controls/diagrams-and-maps/map/how-to/load-markers-for-area.
