What is the best way to update thousands of placemarks dynamically in Google Earth?

Im using the google earth v1 javascript API to update hundreds of objects moving around in "real-time". I keep track of new, modified, and deleted entities to minimize looping in my javascript while updating placemarks, but still the biggest bott开发者_开发知识库leneck is making the calls to the google earth api. Has anyone else tackled this problem? I've read a bit about dynamically streaming from a KML file on a server, but I need access to the placemark object updates in my javascript code.

There is a v3 of the Google Maps Javascript API, but the Google Earth API is at v1. It's unclear from your question if you are using both API's, and if so, how you are interacting with the Earth API.

If you provide some code showing how you are doing the updates it would be easier to offer advice on how to optimize.

That said it sounds like using straight KML with incremental Updates is the way to go for your use case, and you can still access individual placemarks using the getElementByUrl() method

To put a bow on this question. Using dynamic KML files is one way to do this if you dont need to do anything complicated with the data other than display it to the user. Because I need to do work on the data inside the webclient, I ended up using json to transfer the data and then using google.earth.executeBatch to execute my google earth api calls in the most efficient manner.

Have you looked at using Google Fusion Tables? It doesn't use the GE plug-in so....
