Excellent, thanks for the advise. Probably server side clustering would be
more suitable as all the results need to "be" there. However, what about KML
overlays or Fusion tables? Has anybody had much experience with either of
these and can comment on the performance?
Thanks,
Henri

btw, that is only one approach.
Doing server side 'clustering' might be better suited (rather than
just picking a sample). There are various ways to do that.

Or you can just outsource it

one of a few sites offering it :)

Ok, that particular map is not using millions of markers, but the same
technique works for bigger datasets. (I just dont have any big
datasets using v3 of the maps api)
The biggest issue is deciding which features to show as the 'sample'.
Picking random works reasonably well. But there are more elaborate
ways of doing it. You could perhaps pick the top rated (if your
dataset has that)

Go back a step and re-examine your needs. A viewer isn't goimg to get
much value out of a map with millions of markers on it, so you could
perhaps think about what you want to actually show at any given time
(perhaps from an available pool of millions of markers)
