So it's not consistent in the CAP Theorem sense. Comparing it with other databases that don't lose writes and don't have split brain issues makes no sense
- pi-e-sigma 3y agoIt is always consistent because it is a single storage database with multiple access points. It's not distributed data so CAP theorem doesn't even apply to it.
- dikei 3y agoOracle RAC is a shared storage system, every database instances write to same datastore, so as long as a transaction is committed by one node, it'll be seen by other nodes. Of course, the issue with all shared-storage systems is how much it costs to have a reliable and fast shared storage.
