> SPARK-47372 introduced the ability for the RocksDB state provider to big-endian encode values so that they could be range scanned. However, signed support for Byte types [was missed|https://github.com/apache/spark/blob/1efbf43160aa4e36710a4668f05fe61534f49648/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/state/RocksDBStateEncoder.scala#L326], even though Scala Bytes are [signed|https://www.scala-lang.org/api/2.13.5/scala/Byte.html].
