Struct mz_persist::indexed::snapshot::TraceSnapshot

source · [−]

pub struct TraceSnapshot {
    pub ts_upper: Antichain<u64>,
    pub since: Antichain<u64>,
    /* private fields */
}

Expand description

A consistent snapshot of the data that is currently physically in the trace bucket of a persistent crate::indexed::arrangement::Arrangement.

Fields

ts_upper: Antichain<u64>

An open upper bound on the times of contained updates.

since: Antichain<u64>

Since frontier of the given updates.

All updates not at times greater than this frontier must be advanced to a time that is equivalent to this frontier.
