   Hi @4ertus2, looking at the code, the Parquet Writer does not do anything special with high-precision decimal, the raw bytes of the un-scaled integer are written through `BYTE_ARRAY` and read back the same way (https://github.com/apache/parquet-java/blob/master/parquet-column/src/main/java/org/apache/parquet/column/values/plain/PlainValuesWriter.java#L52). Since the array is treated as an opaque blob, byte swapping would not be needed. I'll raise a change to add some comments in the code
