Well this is curious... when I added the , at the end, it did load my data. And when I loaded 12 files concurrently, it loaded remarkably quickly - 2m30s for 1.4bn rows. Very nice.
But now with this new syntax, I don't see the 1200% on process iqsrv16 that I saw before (which is I'm guessing 12 concurrent load threads). Instead, I see one java process (for the loader?) with 14% CPU utilization.
10 minutes later... nothing much has happened. Any ideas what I have done wrong?
