> According to the ORC v1 specification ([https://orc.apache.org/specification/ORCv1/]), the SECONDARY (scale) stream in a Decimal column is encoded using Unsigned Integer RLE v1. However, observing the implementation and behavior of the C++ library, it is evident that the Signed Integer RLE v1 is what is actually used.
