Type Members
- case class TypeEvolution(uniformIcebergCompatibleOnly: Boolean) extends TypeWideningMode with Product with Serializable
Type changes that are eligible to be applied automatically during schema evolution are allowed.
Type changes that are eligible to be applied automatically during schema evolution are allowed. Can be restricted to only type changes supported by Iceberg.
- case class TypeEvolutionToCommonWiderType(uniformIcebergCompatibleOnly: Boolean) extends TypeWideningMode with Product with Serializable
Type changes that are eligible to be applied automatically during schema evolution are allowed.
Type changes that are eligible to be applied automatically during schema evolution are allowed. Can be restricted to only type changes supported by Iceberg. Unlike TypeEvolution, this also allows widening
totofrom, and for decimals, widening to a different decimal type that is wider han both input types. Use for example when merging two unrelated schemas and we want just want to find a wider schema to use.

- case object AllTypeWidening extends TypeWideningMode with Product with Serializable
All supported type widening changes are allowed.
- case object AllTypeWideningToCommonWiderType extends TypeWideningMode with Product with Serializable
All supported type widening changes are allowed.
All supported type widening changes are allowed. Unlike AllTypeWidening, this also allows widening
totofrom, and for decimals, widening to a different decimal type that is wider than both input types. Use for example when merging two unrelated schemas and we want just want to find a wider schema to use. - case object NoTypeWidening extends TypeWideningMode with Product with Serializable
No type change allowed.
No type change allowed. Typically because type widening and/or schema evolution isn't enabled.
