Hi Amudhan,
Please go through the following that would clarify up-gradation concerns
from DHT to RIO in 4.0
1. RIO would not deprecate DHT. Both DHT and RIO would co-exist.
2. DHT volumes would not be migrated to RIO. DHT volumes would still be
using DHT code.
3. The new volume creation should specifically opt for RIO volume once
RIO is in place.
4. RIO should be perceived as another volume type which is chosed
during volume creation
just like replicate, EC which would avoid most of the confusions.
5. RIO will be alpha quality (in terms of features and
functionality) when it releases with 4.0, it is a tech preview to get
feedback from the community.
6. RIO is not a blocker for releasing 4.0, so if said alpha tasks
are not met, it may not be part of 4.0 as well
Hope this clarifies volume compatibility concerns from a distribute
layer perspective in 4.0.
Thanks,
Shyam
