Leadspace has 2 stages our Segment Cards go through:
Processing - enrichment/expansion, suppression
Export - transfer the processed data and create a file
In any of these stages, we could timeout by way of slowness or it gets stuck. When we timeout during the processing stage, we send the processed data and transfer it to the export stage. If this happens, the output file will be available and the segment will be marked as "partially completed" since not all of the input data was processed.
