MergedSubscriptionCheckpoint

laminar_core::checkpoint::subscription

Struct MergedSubscriptionCheckpoint 

Source 
pub struct MergedSubscriptionCheckpoint {
    pub manifest: SubscriptionCheckpointManifest,
    pub ranges: Vec<NodePartitionRange>,
}
Expand description

Whole-cluster stream cut reconstructed from exact participant manifests.

Fields§

§manifest: SubscriptionCheckpointManifest

Canonical checkpoint manifest exposed to committed readers.

§ranges: Vec<NodePartitionRange>

Exact newly committed range per output partition.

Implementations§

Source§

impl MergedSubscriptionCheckpoint

Source

pub fn validate_continuity( &self, predecessor: Option<&SubscriptionCheckpointManifest>, ) -> Result<(), SubscriptionContractError>

Validate this cut’s starting frontiers against an explicitly loaded predecessor.

A missing predecessor is valid only for ranges beginning at sequence zero. A stream absent from the predecessor is a new generation and follows the same rule.

§Errors

Returns a distribution mismatch or the first partition sequence gap.
