Replicas are selected in a large distributed network, and the roles for these replicas are identified. In one example, a leader is selected from among candidate computing clusters. To make this selection, an activity monitor predicts or monitors the workload of one or more clients. Different activities of the workload are given corresponding weights. The delay in performing requested activities, modified by these weights is found, and the candidate leader with the lowest weighted delay is selected as the leader.

Distributed database configuration

Replicas are selected in a large distributed network, and the roles for these replicas are identified. In one example, a leader is selected from among candidate computing dusters. To make this selection, an activity monitor predicts or monitors the workload of one or more clients. Different activities of the workload are given corresponding weights. The delay in performing requested activities, modified by these weights is found, and the candidate leader with the lowest weighted delay is selected as the leader.

Replicas are selected in a large distributed network, and the roles for these replicas are identified. In one example, the role of voting is assigned to a number of computing clusters. To make this selection, a task assigning service finds a candidate leader and M computing clusters to be used as voters. This selection may be based on finding latencies between the M computing clusters and the leader.

Distributed storage system with replica selection

Replicas are selected in a large distributed network, and the roles for these replicas are identified. In one example, an indication that a number N of clusters are to be assigned a replica role and a second number M of the replica-role assigned clusters are to be assigned to a voting role. N computing clusters are selected using workload data, and M of the clusters are assigned to a voting role.
