Review Comment:
If 0.4 is not working on arm currently - wouldn't it not be better for arm
deployments to explicitly set it to ROCKSDB ? (in other words, not to change
the default ?)
To put it differently, my main concern is failure of existing deployments
... in our case, for example, we do not set this config (though we are still in
testing phase) - and we would typically expect a patch to work reasonably as is
with existing config (between minor or major versions, there will be a lot more
scrutiny).
