}

Planner proof that a final operator has a stable, recoverable output distribution.

Fields

version: u16

Exact certificate envelope format.

protocol_version: SubscriptionProtocolVersion

Subscription protocol used by the output.

stream_id: String

Canonical catalog stream name.

catalog_generation: u64

Monotonic durable catalog incarnation.

stream_generation: StreamGeneration

Derived durable incarnation identity.

final_operator_id: String

Stable final graph operator identity.

distribution: OutputDistribution

Certified output-to-partition mapping.

schema_fingerprint: SubscriptionDigest

Fingerprint of the unchanged user output schema.

changelog_mode: ChangelogMode

Changelog representation emitted by the final operator.

history_retention_bytes: u64

Maximum committed output bytes retained for epoch replay; zero admits tail only.

query_fingerprint: SubscriptionDigest

Canonical query fingerprint.

pipeline_identity: PipelineIdentity

Complete pipeline/state ABI identity.

Implementations

impl OutputDistributionCertificate

pub fn validate( &self, key_group_count: KeyGroupCount, ) -> Result<(), SubscriptionContractError>

Validate the canonical certificate and all external bindings.

Errors

Returns the first non-canonical or mismatched durable binding.

pub fn require_match( &self, expected: &Self, ) -> Result<(), SubscriptionContractError>

Validate exact equality with the certificate selected by the current planner.

Errors

Returns a certificate mismatch when any durable binding differs.

pub fn certifies_keyed_aggregate(&self) -> bool

Whether this certificate represents the initial externally admitted stream class.
