> default page_size of 10000 is huge, and makes it impossible to set a hinted_handoff_throttle_delay_in_ms that works well for both wide rows and narrow.
> at the same time you don't want to make it TOO small because that will hurt performance on the source node (seeking to the hinted row repeatedly).
