Hi, I’m working on an application that will be spread across many (150-200) data centers. I had a great chat with Adron at the Seattle Riak Office Hours and I think that Riak can provide the backbone of the solution. Adron is a great help but I have come away with (or have come up with) two more questions.
1. Does riak support specifying bucket level multi data center replication? There is a single master data center that has all of the data, and that central cluster replicates a single different bucket to each of the remote data centers. Its a hub/spoke model where something at the hub has a view of the full data set and something at a spoke end only has a view of a single, unique bucket. 2. What would be the best way to setup a priority replication strategy? There is always a link between the main dc and the spoke dcs, but sometimes its a big fast link and we'd want to do a full replication and sometimes its the equivalent of a 56k modem and we only want to replicate time critical data. I think riak can handle this by using the real-time sync for critical data and the full-sync for a full sync. Will that work or is that asking for trouble running both styles? And there was a small note in the docs<http://docs.basho.com/riakee/latest/cookbooks/Multi-Data-Center-Replication-Architecture/> that says, " ...there are two primary modes of operation..." are there other, secondary modes of replication or is this me over-parsing the docs? Thank you, Pat
