Hi,

 

How is data replicated in Kudu? My understanding is that kudu has one replica of all data and 2 replicas with operational logs. From the apache docs i get this "Kudu does not replicate the on-disk storage of a tablet,
but rather just its operation log. The physical storage of each replica of a tablet is fully decoupled."

 

In case of a disk failure, if the disk contains the actual data and not operation log, how is it recovered??
