---------------------------------------
siddharthteotia opened a new pull request #1443: ARROW-1946: [JAVA] Add APIs to
decimal vector for writing big endian data
URL: https://github.com/apache/arrow/pull/1443
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.
