Enhanced Compute Engine CPU usage

[cassidy]

Looking for some insight in the Enhanced Comput Engine's CPU usage on a Capacity.

I (think) I'm finding that if I try to link to a large Dataflow (30M+ records, 20 columns), the Service is using the Enhanced Compute Engine and loading that table into memory.  It pushes my P1 Capacity CPU to increase 10-15% and stay there.

Is that expected behavior that the CPU is consumed constantly by the Ehanced Compute Engine?

I've experienced this before where I was convinced linking Dataflows was the right idea until it throttled my Capacity.
