Johan Lasperas updated SPARK-59342:
-----------------------------------
Affects Version/s: 4.4.0
(was: 4.3.0)
> Allow configuring schema alignment behavior for DSv2 writes
> -----------------------------------------------------------
>
> Key: SPARK-59342
> URL: https://issues.apache.org/jira/browse/SPARK-59342
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.4.0
> Reporter: Johan Lasperas
> Priority: Major
> Labels: pull-request-available
>
> Allow connectors configuring following schema alignment behavior:
> * allow writes under spark.sql.storeAssignmentPolicy=LEGACY
> * accept implicit casts at analysis, and rely on execution time checks to
> catch malformed values or overflows
> The proposal is to extend the DSv2 interface to allow configuring this
> behavior per table:
>
> {code:java}
> public interface Table {
> ...
> default SchemaAlignmentConfig schemaAlignmentConfig() {
> return SchemaAlignmentConfig.DEFAULT; }
> }
> public interface SchemaAlignmentConfig {
> default boolean allowLegacyStoreAssignmentPolicy() {
> return false;
> }
> default boolean deferCastValidationToRuntime() {
> return false;
> }
> }
> {code}
>
