I have a question about how the feature merger works. As a background to what I'm doing, my workbench that takes a DGN file and converts some levels to shapefiles. During the processing I seperate the metadata features, and extract some of the text (approved date, drawing title, etc.), which is aggregated down to one feature for the document.
I'm trying to join this information back to the model features using a feature merger, so each feature has the date, etc. as an attribute. I have 29000 line features going into the requestor port, and 1 no geometry feature going into the supplier port. the FME log records messages like this:
Performing low-level intersection at phase #3... 100% done
Hit data-shattering case as 4423 new nodes were created after phase 3, compared to 35 nodes created after phase 1.
Completed intersection processing, phase #1. 35 new nodes were generated among 37 intermediate lines
These messages continue for about 30 minutes with ever increasing numbers before FME just stops with no error given.
The feature merger is set to attributes only, so I'm not sure what its intersecting?
Other DGN files pass through the same workbench without issue, and none raise the same log file messages. The only differences between them is the size, the one causing the error is ~6mb and the others are only ~ 3mb.
Thanks,
Andy
