Enum RowGroupPlan 

pub(crate) enum RowGroupPlan {
    Global {
        row_groups: Option<Vec<usize>>,
        selection: Option<RowSelection>,
    },
    PerRowGroup(Vec<RowGroupSelection>),
    Conflicting,
}

Row-selection configuration shared by the Arrow reader builders.

Variants

Global

First select row_groups, if provided, and then apply selection across the concatenated rows from those row groups.

This is formed by ArrowReaderBuilder::with_row_groups and ArrowReaderBuilder::with_row_selection.

Fields

row_groups: Option<Vec<usize>>

selection: Option<RowSelection>

PerRowGroup(Vec<RowGroupSelection>)

Apply each row-group-local selection independently, in the order supplied.

This is formed by with_row_group_selections on the push decoder and async stream builders.

Conflicting

Mutually exclusive global and per-row-group configuration was supplied. This is reported as an error when the reader is built.
