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)
