One TDV cluster node serves as a timekeeper. The timekeeper generates a sequence number for each requested metadata update to the cluster. Changes are then made in FIFO order. The timekeeper also makes sure that triggers operate as configured. Finally, the timekeeper regulates how nodes join or leave the cluster. The timekeeper is otherwise identical to all other TDV server nodes.

Active Cluster automatically determines which TDV Server is the timekeeper. When a cluster is created, the first member is made the timekeeper. If the timekeeper machine goes down, another TDV Server node automatically assumes the timekeeper duties.

Because the timekeeper node performs approximately the same workload as other cluster nodes, it is not necessary to maintain a special server as the timekeeper node.
