> Marking this as beta 1 in the hope I have time to rustle it up and get it reviewed beforehand.
If I do not, I will let it slide, but our behaviour right now is not brilliant for workloads
with a variance in density, and it should not be challenging to make a more targeted decision.
> We can also make use of CASSANDRA-9894 to make column encoding more efficient in many,
even dense, cases.
