Tim Armstrong commented on ARROW-1588: -------------------------------------- Thanks for the CC Wes. Is there some additional context here about the goals? Those decisions (16 bytes and big-endian) are not what I'd expect if we were optimising for in-memory processing speed on little-endian architectures. [~tarasbob] has recently been working on Impala's decimal implementation so may have some thoughts too. > [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. > [~jacq...@dremio.com] [~wesmckinn] If there are any additional items you'd > like to see addressed here please chime in. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
