Hi there,
We know that we need to run repair regularly to make data consistency,suppose
we have DC1 & DC2,
if we add a new DC3 and rebuild from DC1,can we suppose the DC3 is consistency
with DC1 at least at the time when DC3 is rebuild successfully?
Thanks,
Peng Xiao,
No. Rebuilds don't keep consistency as they aren't smart enough to stream
from a specific replica, this all replicas for a rebuild can stream from a
single replica. You need to repair after rebuilding.
If you're using NTS with #racks >= RF you can stream consistently. if this
patch gets in https:/
