I was looking to merge some features to improve the performance of some of my layers on my ArcGIS Server. I have a few very large polyline layers for our fiber network that are exported out of a CAD based program (Mapcom M4) every week and into a GeoDatabase. I did notice that some of the features have the same attributes and fiber ID's, but are separated into up to between 4-15 different lines. When I tested this out and manually dissolved the featueres into one based on fiber ID it drastically improved performance. This would be a significant expense of time to do every week, though, and I was looking to make it part of my Weekly FME Workbench. I just wasn't sure what transformer would make the most sense to use to merge all the features with the same Fiber ID before writing them to the Geodatabase.
