By default views tolerate column type changes in the query and compensate with casts. To disable this feature set `spark.sql.legacy.viewSchemaBindingMode` to `false`. This also removes the clause from `DESCRIBE EXTENDED` and `SHOW CREATE TABLE`. - Since Spark 4.0, The Storage-Partitioned Join feature flag `spark.sql.sources.v2.bucketing.pushPartValues.enabled` is set to `true`. To restore the previous behavior, set `spark.sql.sources.v2.bucketing.pushPartValues.enabled` to `false`. - Since Spark 4.0, the `sentences` function uses `Locale(language)` instead of `Locale.US` when `language` parameter is not `NULL` and `country` parameter is `NULL`. +- Since Spark 4.0, reading from a file data source will correctly respect query options, e.g. delimiters. Previously, the first query plan was cached and subsequent option changes ignored. To restore the previous behavior, set `spark.sql.legacy.readDataSourceCacheIgnoreOptions` to `true`.
