Expand description

Canonical global recovery image selected by one cluster Commit outcome.

Fields§

§version: u32

Capsule payload format.

§attempt: CheckpointAttempt

Exact checkpoint attempt represented by this image.

§deployment_id: String

Durable deployment incarnation that owns the image.

§pipeline_identity: PipelineIdentity

Exact logical pipeline and recovery-state ABI.

§assignment_fence: CheckpointAssignmentFence

Exact vnode assignment and process roster covered by the image.

§seal_inventory_sha256: String

SHA-256 of the canonical state-backend seal inventory.

§participants: Vec<ParticipantRecoveryRef>

Participant artifacts, sorted by participant ID and exactly covering the fence.

§source_offsets: BTreeMap<String, BTreeMap<String, String>>

Complete per-source connector offsets in canonical map order.

§source_metadata: BTreeMap<String, BTreeMap<String, String>>

Complete per-source connector metadata in canonical map order.

§source_assignment_versions: BTreeMap<String, NonZeroU64>

Assignment version captured by each partitioned source, in canonical source-name order.

The map may be sparse because runtime topology determines which sources require an assignment cut. Every populated version must match assignment_fence.

§source_watermarks: BTreeMap<String, i64>

Per-source event-time watermarks in canonical map order.

§cluster_watermark: CheckpointWatermark

Cluster-wide event-time state at this exact cut.

§recovery_watermark_frontier: Option<i64>

Durable numeric event-time frontier restored with this cut.

This equals the active watermark for an active cut, is absent for an uninitialized cut, and may retain the last active value for an idle cut.

§portable_state_sha256: String

SHA-256 of the canonical portable non-vnode state image.
