Abstract
Described herein are technologies directed to lazy lock queue reduction in computing clusters. The disclosed lazy lock queue reduction techniques can be performed in preparation for cluster group changes. Prior to a cluster group change operation, such as a merge or a split of a node with a group, a notification of a planned group change operation can be sent to the nodes of a group. In response to the notification, the nodes of the group can perform lazy lock queue reduction techniques disclosed herein. In one disclosed lazy lock queue reduction technique, a node can set a drain goal for a lazy lock queue, and the node can drain the lazy lock queue according to the drain goal. In another disclosed lazy lock queue reduction technique, a node can set an age limit for lazy lock queue entries, and the node can remove lazy lock queue entries which are expired or over the age limit.
