Abstract
Various embodiments of methods and systems for dynamically switching to a new coordinator resource are disclosed. In one embodiment, a method involves receiving information identifying a new coordinator resource for use by a cluster; detecting whether each of the nodes within the cluster is committing to use the new coordinator resource; and switching from an existing coordinator resource to the new coordinator resource, in response to detecting that each of the nodes within the cluster is committing to use the new coordinator resource. This method can be performed concurrently with normal cluster operations, and thus the cluster need not be disabled to perform the switchover.
