Class UnnestOptions

java.lang.Object

org.apache.datafusion.UnnestOptions

public final class UnnestOptions
extends Object

Configuration knobs for DataFrame.unnestColumns(UnnestOptions, String...), mirroring DataFusion's UnnestOptions. Defaults match upstream: preserveNulls = true.

Per-column recursion (DataFusion's recursions) is intentionally not exposed yet — it needs a richer column-pair representation and is filed separately.
