摘要:
A method and apparatus for managing locks in a database system is provided. A master node grants a lock on a first resource and a group of resources that includes the first resource to a first requester node. The requester node receives a mapping corresponding to the group of resources that may indicate that a lock already exists for a second resource in the group. If the requester node desires a lock on a resource located in the group, the requester node grants itself the lock without notifying the master node. A second requester node requests a lock for a particular resource in the group of resources. The first requester node grants the lock on the particular resource and updates the mapping to indicate that a different node holds a lock for the particular resource.
