Note that the current getCover option just rasterizes at 10x resolution and then aggregates (see here). Future implementation should avoid this so that one never needs 100x memory. Shouldn't be difficult - we just advance x and y at 0.1 rather than 1, and add 0.01 to the pixel at the rounded-down values of x and y.

Really enjoying how quick fasterize is. Do you still plan to implement the getCover option from raster? I'm currently trying to get rid of coastal cells on a rather large raster and this would be super useful.
