Enum DocumentResolvedMutation 

pub enum DocumentResolvedMutation {
    Put {
        collection: QualifiedCollection,
        document_id: String,
        surrogate: Surrogate,
        pk_bytes: Vec<u8>,
        value: Vec<u8>,
        precondition: Option<Vec<u8>>,
        resolved_sum_targets: Vec<ResolvedSumTarget>,
    },
    Delete {
        collection: QualifiedCollection,
        document_id: String,
        surrogate: Surrogate,
        pk_bytes: Vec<u8>,
        precondition: Option<Vec<u8>>,
        resolved_sum_targets: Vec<ResolvedSumTarget>,
    },
}

One row mutation a resolved document write applies.

precondition is the resolve→apply drift check, not business logic: None requires the row absent, Some(bytes) requires it hold exactly bytes (==). A surrogate-existence check would miss a concurrent write that changed content without deleting the row — the lost update this precondition prevents.

Variants

Put

Store value for document_id, replacing whatever is there.

Fields

collection: QualifiedCollection

document_id: String

User-facing primary key, as RETURNING and CDC name the row.

surrogate: Surrogate

Catalog-bound identity; the handler hex-encodes it for the row key.

pk_bytes: Vec<u8>

Raw primary-key bytes, for follower-side WAL decode rebind.

value: Vec<u8>

Pre-encode MessagePack body — see this module’s doc.

precondition: Option<Vec<u8>>

Raw stored bytes the resolve read, or None for an absent row.

resolved_sum_targets: Vec<ResolvedSumTarget>

(target collection, join value) → target row surrogate, resolved by the Control Plane (Data Plane has no PK→surrogate map).

Delete

Remove document_id.

Fields

collection: QualifiedCollection

document_id: String

surrogate: Surrogate

pk_bytes: Vec<u8>

precondition: Option<Vec<u8>>

Raw stored pre-image the resolve read and decided the policy against.

resolved_sum_targets: Vec<ResolvedSumTarget>

See DocumentResolvedMutation::Put::resolved_sum_targets.

Implementations
