Variants

Detect
[−]

The detect request of itself.

[−]

Fields of Detect

tp: DetectTypetxn_ts: TimeStamplock: Lockdiag_ctx: DiagnosticContext
DetectRpc
[−]

The detect request of other nodes.

[−]

Fields of DetectRpc

stream: RequestStream<DeadlockRequest>sink: DuplexSink<DeadlockResponse>
ChangeRole(Role)
[−]

If the node has the leader region and the role of the node changes, a ChangeRole task will be scheduled.

It’s the only way to change the node from leader to follower, and vice versa.

ChangeTTL(Duration)
[−]

Change the ttl of DetectTable
