Expand description

A description of an active copy to sink from the coordinator’s perspective.

Fields§

§conn_id: ConnectionId

The ID of the connection which created the subscribe.

§tx: Sender<Result<ExecuteResponse, AdapterError>>

The result channel for the COPY ... TO statement that created the copy to sink.

§cluster_id: ClusterId

The ID of the cluster on which the copy to is running.

§depends_on: BTreeSet<GlobalId>

The IDs of the objects on which the copy to depends.

Implementations§

source§

impl ActiveCopyTo

source

pub fn retire_with_response(self, response: Result<u64, Error>)

Retires the copy to with a response from the controller.

Unlike subscribes, copy tos only expect a single response from the controller, so process_response and retire are unified into a single operation.

Either this method or retire must be called on every copy to before it is dropped.

source

pub fn retire(self, reason: ActiveComputeSinkRetireReason)

Retires the copy to with the specified reason.

Either this method or retire_with_response must be called on every copy to before it is dropped.
