Expand description

SchemaChangeOutcome

Durable terminal or resumable outcome of one admitted proposal.

Variants§

NoOp

The exact proposal was already reflected by the accepted head.

Fields

§accepted_head: ExpectedAcceptedHead

Accepted head retained by the no-op.

Applied

The proposal published a new accepted head atomically.

Fields

§accepted_head: ExpectedAcceptedHead

Newly accepted database-wide head.

Pending

Bounded activation work remains under one durable job.

Fields

§job: SchemaChangeJob

Resumable job identity.

§candidate_head: ExpectedAcceptedHead

Candidate head reserved by the pending work.

Aborted

The authorized owner aborted a pending activation.

Fields

§accepted_head: ExpectedAcceptedHead

Accepted database-wide head after retiring the activation.
