Enum DeltaFileRepartitioning 

Source 
#[non_exhaustive]
pub enum DeltaFileRepartitioning {
    FillMissingParallelism,
    Rebalance,
}
Expand description

Controls when DataFusion may split NativeAsync Parquet files into ranged scan tasks.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

FillMissingParallelism

Split files only when whole-file planning produced fewer partitions than the target.

§

Rebalance

Let DataFusion rebalance file groups even when they already fill the target.
