Thanks for the report, @thecatontheflat! I think this issue has the same root cause as #1315, so I'm going to merge the two issues. I've copied over some details from this report as well. If you need a workaround in the meantime, I found that running weld first, followed by join, will complete. The weld step is still slow (also tracked by the issue above), but keeps a more reasonable memory footprint for a file this size.

The workaround has worked! Thanks for the suggestion!
