RasterCheckPointer
From fmepedia
The RasterCheckPointer is a Workbench Transformer
The transformer sets a checkpoint in the raster processing which forces previous processing to occur immediately and saves the current state to disk once complete. This is an advanced transformer to optimize raster processing and should not be overused. It is most useful following slow processing steps such as the Rasterizer or Reprojector or before multiple cloning processing steps such as the RasterTiler, RasterPyramider, Cloner or writers with feature type fanout.
See VirtualEarthHTMLCreator for an example workspace containing RasterCheckPointer.
