Source 
fn committed_lsn(
    exports: &[GlobalId],
    uppers: &BTreeMap<GlobalId, Antichain<Lsn>>,
) -> Option<Lsn>
Expand description

The Lsn that every export in exports has durably committed through.

None while some export has not committed beyond the ingestion’s as_of, and once every export’s upper is empty, which happens when the source is dropped.
