Module tikv::server::lock_manager::deadlock[−][src]

Structs

DetectTable	Used to detect the deadlock of wait-for-lock in the cluster.
Detector	Detector is used to detect deadlocks between transactions. There is a leader in the cluster which collects all `wait_for_entry` from other followers.
Inner
Locks	`Locks` is a set of locks belonging to one transaction.
RoleChangeNotifier	`RoleChangeNotifier` observes region or role change events of raftstore. If the region is the leader region and the role of this node is changed, a `ChangeRole` task will be scheduled to the deadlock detector. It’s the only way to change the node from the leader of deadlock detector to follower, and vice versa.
Scheduler	`Scheduler` is the wrapper of the `FutureScheduler<Task>` to simplify scheduling tasks to the deadlock detector.
Service

The leader region is the region containing the LEADER_KEY and the leader of the leader region is also the leader of the deadlock detector.
