Is there an equivalent of Marker manager in Google Maps in MapKit Framework which help cluster the markers in certain zoom levels?
What Marker Manager does is as follows: "Adding a large number of markers to a Google map may both slow down rendering of the map and introduce too much visual clutter, especially at certain zoom levels. The marker manager utility provides a solution to both of these issues, allowing efficient display of hundreds of markers on the same map and the ability to specify at which zoom levels markers should appear."
