Examples of voldemort.client.scheduler.AsyncMetadataVersionManager

voldemort.client.scheduler.AsyncMetadataVersionManager
The AsyncMetadataVersionManager is used to track the Metadata version on the cluster and if necessary Re-bootstrap the client. During initialization, it will retrieve the current version of the cluster.xml and then periodically check whether this has been updated. During init if the initial version turns out to be null, it means that no change has been done to that store since it was created. In this case, we assume version '0'. @author csoman
