BryanCutler commented on issue #1443: ARROW-1946: [JAVA] Add APIs to decimal
vector for writing big endian data
URL: https://github.com/apache/arrow/pull/1443#issuecomment-354513366
This seems ok to me, but I don't really know how many users have BE
decimals. Could you clarify a little if this is still useful for Dremio since
you've moved to LE, or is it just something that might help other users if they
have this type of data?

> Key: ARROW-1946
> URL: https://issues.apache.org/jira/browse/ARROW-1946
> Project: Apache Arrow
> Issue Type: Bug
> Components: Java - Vectors
> Reporter: Siddharth Teotia

>
> We recently moved Dremio to LE Decimal format (similar to Arrow). As part of
> that we introduces some APIs in decimal vector which take a big endian data
> and swap the bytes while writing into the ArrowBuf of decimal vector.
> The advantage of these APIs is that caller would not have to allocate an
> additional memory and write( and read) source big endian twice for swapping
> into new memory and using that to write into the vector.
> We can directly swap bytes while writing into the vector -- just read once
> and swap while writing.
