Subject Efficiency of Cross Data Center Replication...?
Date Wed, 16 Nov 2011 20:33:50 GMT
Hi All,

I have a question about inter-data centre replication : if you have 2 Data
Centers, each with a local RF of 2 (i.e. total RF of 4) and write to a node
in DC1, how efficient is the replication to DC2 - i.e. is that data :
 - replicated over to a single node in DC2 once and internally replicated
 - replicated explicitly to two separate nodes?

Obviously from a LAN resource utilisation perspective, the former would be

Many thanks,
