Struct CheckpointTuple 

pub struct CheckpointTuple {
    pub config: RunnableConfig,
    pub checkpoint: Checkpoint,
    pub metadata: CheckpointMetadata,
    pub pending_writes: Vec<PendingWrite>,
    pub parent_config: Option<RunnableConfig>,
}

Complete checkpoint tuple with all context

Combines checkpoint data with its metadata, configuration, and pending writes. This is the primary structure returned from checkpoint storage for recovery.

Fields

config: RunnableConfig

Configuration containing thread_id, checkpoint_id, and checkpoint_ns

checkpoint: Checkpoint

The checkpoint itself

metadata: CheckpointMetadata

Checkpoint metadata

pending_writes: Vec<PendingWrite>

Incremental writes since this checkpoint

Used for crash recovery: these writes completed after the checkpoint and before the next checkpoint, so they don’t need to be re-executed.

parent_config: Option<RunnableConfig>

Parent checkpoint configuration

Used for time-travel navigation.
