Struct mz_storage_client::controller::ExportState

pub struct ExportState<T> {
    pub description: ExportDescription<T>,

Expand description

State maintained about individual exports.

Fields§

§description: ExportDescription<T>

Description with which the export was created

§read_capability: Antichain<T>

The capability (hold on the since) that this export needs from its dependencies (inputs). When the upper of the export changes, we downgrade this, which in turn downgrades holds we have on our dependencies’ sinces.

§read_policy: ReadPolicy<T>

The policy to use to downgrade self.read_capability.

§storage_dependencies: Vec<GlobalId>

Storage identifiers on which this collection depends.

§write_frontier: Antichain<T>

Reported write frontier.

Implementations§

fn cluster_id(&self) -> Option<StorageInstanceId>
