Following what Andrea said,
we are handling raster data in the order of hunderds of thousands with the
standards geoserver but also in the order of millions wi customized
geoserver deployments and the imagemosaic.
I believe that first you need to understand what the pattern of usage or
some other grouping condtion that might apply to your data then we can see
waht the best way to handle them is.
As Andrea says, are we talking about millions of orthos? Time series data?
Thematic layers?
Regards,
Simone.
