Description

Because changefeeds restart when a range splits, changefeeds can fall behind at scale (where performance matters immensely and many range splits take place). This is especially pronounced in the webhook sink when paired with cdc-sink.

We should explore ways to minimize the impact of range splits on changefeeds.
