Currently we store `BigDecimal` as bytes, but because the ordering of `BigDecimal` is different from bytes, we might have to introduce the `BigDecimal` into the data representation layer. Checked the decimal value support in other systems, and most of them support up to 38 precision digits. Wondering the reason behind that, and if we can store the value in 136-bit format (1 sign bit, 6 scale bit, 129 precision bits) if we also limit the 38 precision digits. If we can keep the ordering the same for `BigDecimal` and underlying bytes, we can reuse the bytes comparing logic and not introducing `BigDecimal` special ordering handling. -- This is an automated message from the Apache Git Service.
