Slides: https://www.slideshare.net/DataStax/operations-consistency-failover-for-multidc-clusters-alexander-dejanovski-the-last-pickle-cassandra-summit-2016 | Cassandra's support for multiple data centers can bring massive benefits to an organization, however it can also bring painful operational lessons. While there is no recipe for trouble free mutli DC clusters, the best approach is to understand why you are using one, what Cassandra supports, and how it does it. With this knowledge in your toolkit you will have a better chance of fixing the sort of gremlins that can trouble a globally distributed database. In this talk Alexander Dejanovski, Consultant at The Last Pickle, will outline the motivations people typically have for running a multi DC cluster. He will also look at how multiple DC's are supported through all areas of the Cassandra, how it impacts your application and operations, and how you can always blame the network.
