REMASTERING FOR ASYMMETRIC CLUSTERS IN HIGH-LOAD SCENARIOS

Techniques are provided for remastering resources based on node utilization. According to one such technique, resources are remastered in response to the over-utilization of the node that currently masters those resources. The utilization of each node is tracked, and when a particular node's utilization exceeds a specified threshold, selected resources that are currently mastered by that node are remastered so that nodes other than the particular node become the new masters for the selected resources. Each node's utilization is based on that node's capacity, and each node's capacity may differ. According to an aspect of one technique, each node's capacity is based on that node's processing resources and memory resources. Remastering resources in this manner tends to reduce the average amount of time taken for nodes to handle requests for the resources that they master.
