Hi, I'm new to the maps API, currently just playing with it. I wish to display an overlay on the map which will be composed of markers and info windows. I plan to load the data to the map with ajax calls which will query a DB (I assume I'll have around 20k records).
Obviously I won't query the whole DB every time a users loads the page, I guess I'll probably need to query data for the currently displayed area + some margin. I assume this is a standard question that everyone who added some overlay data on a map handled. So can anyone tell me what is the common approach? How much data to query? when to load it? how much data to keep in the JS memory? (I assume having 20K records on the map will make the browser heavy) Thanks! -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
