pub struct KgSnapshot {
    pub id: SnapshotId,
    pub namespace: String,
    pub parent_id: Option<SnapshotId>,
    pub message: String,
    pub author: Option<String>,
    pub created_at: i64,
    pub entity_count: u64,
    pub edge_count: u64,
}

Immutable point-in-time capture of a namespace’s entity and edge set.

id is the SHA-256 hash of the deterministically serialized archive. The archive itself is stored separately in kg_snapshot_archives.
