[Gluster-users] New halo for "simple" 2 nodes asynchronous replica (async master-master)
Hi, is it possible to use the new "halo" feature to create a replica 2 volume on 2 bricks that are located in 2 different regions (10+ ms latency) so to be able to write to both nodes from each region without the need to a synchronous confirmation of the other node? Does this page includes the most up to date /complete docs about that feature? https://github.com/gluster/glusterfs/issues/199 I guess it would be: halo-min-replicas = 1 but what about: halo-latency = ??? If I understood it correctly, in a similar setup I could write to node1 and the write would be fast as a local write, but in background halo would propagate the write to the node in the other region just after my write. So this could be something similar to a master-master mysql asynchronous binlog replica: if you know that no one work on the same file/record on both nodes at the same time then it works.
