Understanding table limits for the Merge function in MapInfo Pro Advanced

Products affected: MapInfo Pro  Advanced™
MapInfo Pro Advanced Users have asked Support if there is a limit to the number of rasters that can be merged in
MapInfo Pro Advanced currently (MapInfo Pro 17.0.2).
Although specific performance testing has been performed to create a matrix, there is a limit to the number of files which can be merged
of ~ 2000 files.
There exists a threshold on the number of opened raster file handles in the Raster SDK of ~2000 files (~2048).
