Enum parquet2::metadata::ColumnOrder

source · [−]

pub enum ColumnOrder {
    TypeDefinedOrder(SortOrder),
    Undefined,
}

Expand description

Column order that specifies what method was used to aggregate min/max values for statistics.

If column order is undefined, then it is the legacy behaviour and all values should be compared as signed values/bytes.

Variants

`TypeDefinedOrder(SortOrder)`

Column uses the order defined by its logical or physical type (if there is no logical type), parquet-format 2.4.0+.

`Undefined`

Undefined column order, means legacy behaviour before parquet-format 2.4.0. Sort order is always SIGNED.
