Description
CDC export should (at least in theory) be a lot less impactful on the cluster (latency, cpu, etc)
than the regular changefeed (due to the fact that CDC export, `initial_scan=only` does not
use rangefeed subsystem.).
However, it's not clear
1. What the impact is?
2. How many of the concurrent exports is too many?
