<i>GoshawkDB is unique as it allows you to configure the tolerance to failure independently of the size of the GoshawkDB cluster. For example, you could have a cluster of 5 nodes and require that it continues to operate unless more than 2 nodes become unreachable. Or you could have a cluster of 20 nodes and require that it continues to operate unless more than 3 nodes become unreachable. The only requirement is that if F is the number of unreachable nodes you wish to be able to tolerate, then your minimum cluster size is 2</i>F + 1. You may of course choose to have a cluster size larger than this. Currently no other data store that I&#x27;m aware of offers this flexibility.<p>I fail to see the point of making your cluster unavailable before you&#x27;ve lost so many nodes that you no longer have a quorum. It seems odd to have a cluster that can handle e.g. 4 node failures, and take it offline after only 2. Why would anyone want a feature like that?
