Map your data with the Maps API and Fusion Tables

引用介绍:

If you have ever tried to plot a very large number of overlays on an API map you have probably reached a point at which the performance of your application begins to suffer. With one hundred or so markers, most browsers cope just fine, and clustering solutions like Fluster can help support more. But if you have thousands of overlays that you wish to show, rendering them individually can be problematic.

The Maps API v3 now offers two solutions to this problem. If you have a large volume of geospatial data that can be served as KML, the KmlLayer class can render up to 50,000 features as an overlay that does not impact performance on any browser. To support data sets that are structured as tables, such as a database or spreadsheet, we have also now added the FusionTablesLayer class for rendering data stored in Google Fusion Tables.
