> Modern client drivers also have ways to “downgrade” the CL of requests, in case they
fail. E.g. for the Java driver:

Quick note from a driver dev's perspective: Mark, yours sounds like a
bad use case for a downgrading retry policy. If your cluster has an RF
of 2, and your app requires CL.QUORUM, a downgrading policy will, e.g.
try at CL.QUORUM and downgrade below your required CL; or try at
CL.ALL, then fail and downgrade to CL.QUORUM or an equivalent, which
is what your app needs in the first place.
