Here cross-dc forwarding means the fact of optimizing cross-dc replication. If we're in some DC1 and need to replicate a write to 3 replicas in DC2, we send just one message cross-DC, and they have the one node in DC2 forward the message to the 2 other replica, instead of just sending 3 message cross-DC. -- Sylvain >> >> -- >> Sylvain >> >> On Thu, Mar 29, 2012 at 9:33 PM, Mohit Anchlia <mohitanch...@gmail.com> >> wrote: >> > Any updates? >> > >> > >> > On Thu, Mar 29, 2012 at 7:31 AM, Mohit Anchlia <mohitanch...@gmail.com> >> > wrote: >> >> >> >> This is from NEWS.txt.
