- In Spark 3.2, `spark.sql.adaptive.enabled` is enabled by default. To
restore the behavior before Spark 3.2, you can set `spark.sql.adaptive.enabled`
to `false`.
+ - In Spark 3.2, the meta-characters `\n` and `\t` are escaped in the
`show()` action. In Spark 3.0 or earlier, the two metacharacters are output as
it is.
Review comment:
Ur, do we handle this in complex types like `Array/Map/Struct`? The
current AS-IS PR seems to handle only the top-level string type. If we don't
support complex types, we need to narrow down more specific about the benefit.
