FME 2017.0 (17271) on Windows Server 2008 R2 Standard.
I'm using PointOnAreaOverlayer to add 3 attributes from a polygon layer (non-overlapping polygons) to a point layer. The polygons are coming from ArcSDE (SQL Server) and the point data comes from SQL Server with geometry in the Geometry data type. The 3 attribute columns already exist in the point layer and I'm using fme_db_operation to UPDATE them in the Writer. Between the PointOnAreaOverlayer and Writer I'm using AttributeManager to assign the polygon attribute values to the appropriate SQL Server table attributes.
If I don't use any parallel processing in the PointOnAreaOverlayer, the translation works and takes about an hour per million points. However, if I group by one of the point layer fields (4 distinct values) and use Aggressive parallel processing, it cuts that time to 40 minutes per million points, but the polygon attributes do not get added to the point data. When I inspect the output from AttributeManager, the attributes that should have been added from the polygon layer are <missing>.
Any ideas?
I'm going to try not exposing the point data attributes to be updated and instead rename the polygon attributes in AttributeManager. However I would expect both methods to work.
