Copy on Right B Tree

A copy on riht btree is a thing, and it's very useful. It's sort of a step from mutable betree. Just like with immutability, all pages are immutable. And if we go one step further, and on top of just immutability,. we also add buffering. This allows you to avoid doing something like rite a headlogging - this may make sense efor some use cases. There are many talks that i've seen line on the subject, and there are some presentations that you can dig out.
