Struct CheckpointManifestV2 

pub struct CheckpointManifestV2 {
    pub version: u32,
    pub checkpoint_id: CheckpointId,
    pub epoch: u64,
    pub timestamp_ms: u64,
    pub operators: HashMap<String, OperatorSnapshotEntry>,
    pub source_offsets: HashMap<String, SourceOffsetEntry>,
    pub parent_id: Option<CheckpointId>,
    pub watermark: Option<i64>,
    pub total_size_bytes: u64,
}

V2 checkpoint manifest for distributed object-store checkpoints.

This extends the file-system CheckpointManifest with per-operator partition entries, incremental delta support, and source offset tracking suitable for multi-partition recovery.

Fields

version: u32

Manifest format version (always 2 for this type).

checkpoint_id: CheckpointId

Unique checkpoint identifier (UUID v7).

epoch: u64

Monotonically increasing epoch number.

timestamp_ms: u64

Timestamp when checkpoint was created (millis since Unix epoch).

operators: HashMap<String, OperatorSnapshotEntry>

Per-operator snapshot entries.

source_offsets: HashMap<String, SourceOffsetEntry>

Per-source offset entries.

parent_id: Option<CheckpointId>

Parent checkpoint ID for incremental checkpoints.

watermark: Option<i64>

Global watermark at checkpoint time.

total_size_bytes: u64

Total size of all checkpoint artifacts in bytes.

Implementations

impl CheckpointManifestV2

pub fn new(checkpoint_id: CheckpointId, epoch: u64) -> Self

Create a new V2 manifest.

Trait Implementations

impl Clone for CheckpointManifestV2

fn clone(&self) -> CheckpointManifestV2

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CheckpointManifestV2

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CheckpointManifestV2

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CheckpointManifestV2

fn eq(&self, other: &CheckpointManifestV2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CheckpointManifestV2

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
