Hi Peter,
You are quite right on the memory limits - especially in the case of row tables. I ended up with a scenario where the data loader added too much data to the system and ideally should have thrown an error during the load. It did - just too late. The row table ended up having more data than could load into memory and the server crashed. Unfortunately, I could never recover other than tearing down the instance and building a new instance - this time using column tables.
Regards,
Bill
