Node clustering configuration is disclosed herein. An example method includes determining nodes of a cluster, each of the nodes having a unique identifier and a cluster identifier for the cluster, determining a voting configuration for the cluster, the voting configuration defining a quorum of master-eligible nodes of the nodes, the voting configuration being adaptable so as to maintain an optimal level of fault tolerance for the cluster, adding and removing nodes that can change the voting configuration, configuring a cluster configuration through an API, and electing one of the master-eligible nodes as a master node.
