Impact of Large Dataset with Group by in Load Statement
While loading a dataset of 100 million records consisting of 5 columns, (one column is doing a Max aggregation function, and the other 4 columns are part of a Group by clause,) the computer crashes. No blue screen. When It crashed with the Group by the whole screen just froze completely, and then it rebooted.
Performing a load without the Group by, then using a Resident load with a Group by, all window objects failed. The desktop just died. I had to force a restart by holding down the power button for 30 seconds. But never had the blue screen in any of this.
Any thoughts on limitations with the Group by that may be contributing to this issue would be most appreciated.
