sealed trait TypeWideningMode extends AnyRef

A type widening mode captures a specific set of type changes that are allowed to be applied. Currently:

  • NoTypeWidening: No type change is allowed.
  • AllTypeWidening: Allows widening to the target type using any supported type change.
  • TypeEvolution: Only allows widening to the target type if the type change is eligible to be applied automatically during schema evolution.
  • AllTypeWideningToCommonWiderType: Allows widening to a common (possibly different) wider type using any supported type change.
  • TypeEvolutionToCommonWiderType: Allows widening to a common (possibly different) wider type using only type changes that are eligible to be applied automatically during schema evolution.

TypeEvolution modes can be restricted to only type changes supported by Iceberg by passing uniformIcebergCompatibleOnly = truet, to ensure that we don't automatically apply a type change that would break Iceberg compatibility.
