ParaView should retain common dataset/array information on its own
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Many file formats are problematic in that they don't include metadata on arrays such as extrema (at one time step or over all time steps), vector magnitude ranges, etc. This results in ParaView spending a lot of time re-running filters that iterate over the data many times in order to obtain this information or avoiding the presentation of this information altogether. ParaView should keep track of this information itself rather than recompute it.
