Struct CoordinatedCommitNamespace 

Source 
pub struct CoordinatedCommitNamespace {
    pub pipeline_identity: PipelineIdentity,
    pub deployment_id: String,
    pub sink_id: String,
}
Expand description

Stable external commit namespace for one deployment incarnation of a logical pipeline sink.

The configured external target already scopes its metadata. The create-once deployment id prevents checkpoint-store resets or two identically configured deployments from sharing a cursor. Pipeline identity plus sink id then binds that deployment to one recovery-compatible logical writer.

Fields§

§pipeline_identity: PipelineIdentity

Canonical logical-pipeline identity used by checkpoint recovery.

§deployment_id: String

Create-once UUID stored with checkpoint decisions and shared by every cluster member.

§sink_id: String

Stable sink registration id within the pipeline.

Implementations§

impl CoordinatedCommitNamespace

Source

pub fn try_new( pipeline_identity: PipelineIdentity, deployment_id: impl Into<String>, sink_id: impl Into<String>, ) -> Result<Self, ConnectorError>

Construct and validate a namespace before any external metadata lookup.

§Errors

Returns a configuration error for a malformed pipeline digest or empty sink id.

Source
