Wes McKinney commented on ARROW-1588:
-------------------------------------
[~tarmstrong] in the not-too-distant future we will be creating a columnar
function kernel library in C++ to process arrays of contiguous decimals
in-memory, so we would want operations like {{arr * 2}], where {{arr}} contains
multiple decimal values in a buffer to evaluate as fast as possible. For the
moment the only place where Arrow users are doing analytics on Decimals in in
Dremio https://github.com/dremio/dremio-oss.
> [C++/Format] Harden Decimal Format
> ----------------------------------

> Key: ARROW-1588
> URL: https://issues.apache.org/jira/browse/ARROW-1588
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, Format
> Affects Versions: 0.7.0
> Reporter: Phillip Cloud
> Assignee: Phillip Cloud
> Fix For: 0.8.0
>
>
> We should finalize and harden the decimal format. The remaining issues are
> officially writing down the choice of making every decimal value 16 bytes and
> byte order.
> For byte order we'll need to run some benchmarks to compare little endian vs
> big endian. I plan to work on this over the next week or two.

> like to see addressed here please chime in.
