Is there a way to get marker clustering (ie makerclusterer) to work with a Fusion Table layer? It seems that you have to assign markers to markerclusterer yet when using a fusion table layer, Google is handling the markers/infowindows? Still trying to figure this fusion table thing out.
Basically looking for a way to cluster large amounts of markers being provided via a Fusion Table
Fusion Tables allows you to view thousands of points at once by using server side rendering (from the google servers). Marker Clusterer solves the problem by building a set of clusters from nearest points (from the clients browser). I wouldn't necessarily use them both at the same time, but it might work for your use case it's up to you.
You can read more information about how they work here:

If you really wanted too you could use the Fusion Tables API to feed the data from Fusion Tables to the Marker Clusterer.
Hope this helps.
