Must be re-implemented using the same approach than ST_D8FlowAccumulation.

Can you explain why we should reimplement ? What has to be changed ?

The current ST_FillSinks (https://github.com/orbisgis/h2gis/blob/raster/1.3.X/h2spatial-ext/src/main/java/org/h2gis/h2spatialext/function/spatial/raster/utility/OpFillSinks.java) function put all the raster in memory so with large DEM with have an out of memory. It'd be nice to use the tile mechanism from JAI operator API.
