True. Various active/active geo-replication solutions have been on the road map for some time, but in each release there are other things deemed more important. :( > Finally, given that ping times between regions are typically in excess > of 200 ms in my case, would you strongly discourage AFR usage? Pretty strongly. The AFR write protocol is quite latency-sensitive. Obviously, this affects performance. Also, as RTT increases it becomes harder and harder to tune things so that network "brownouts" don't become full partitions. If the read-replica selection options worked, then reads should be OK and an almost entirely read-only workload might be OK. Otherwise, I'd say you're likely to have a bad time. _______________________________________________ Gluster-users mailing list [email protected] http://www.gluster.org/mailman/listinfo/gluster-users
