Struct mz_compute::render::continual_task::SinkState

source · 
struct SinkState<D, T> {
    append_times: BTreeSet<T>,
    append_times_progress: Antichain<T>,

    output_progress: Antichain<T>,
}

Fields§

§append_times: BTreeSet<T>

The known times at which we’re going to write data to the output. This is guaranteed to include all times < append_times_progress, except that ones < output_progress may have been truncated.

§append_times_progress: Antichain<T>§to_append: ConsolidatingVec<(D, T)>

The data we’ve collected to append to the output. This is often compacted to advancing times and is expected to be ~empty in the steady state.

§to_append_progress: Antichain<T>§output_progress: Antichain<T>

A lower bound on the upper of the output.
