Struct mz_persist_client::iter::PartIndices

source ·
struct PartIndices {
    sorted_indices: VecDeque<usize>,
    next_index: usize,
}
Expand description

Indices into a part. For most parts, all we need is a single index to the current entry… but for parts that have never been consolidated, this would return entries in the “wrong” order, and it’s expensive to re-sort the columnar data. Instead, we sort a list of indices and then use this helper to hand them out in the correct order.
