Steven Phillips commented on ARROW-617: --------------------------------------- I personally strongly favor simplicity, so if it were up to me, I would choose to go with a single physical type, even though that means we would have to resolve compatibility issues with existing code. I would actually go a step further and ask if we really need all 4 (nano/micro/milli/seconds). Couldn't we just store nanoseconds in all cases? Are we concerned about the cost of conversion? > Time type is not specified clearly > ---------------------------------- > > Key: ARROW-617 > URL: https://issues.apache.org/jira/browse/ARROW-617 > Project: Apache Arrow > Issue Type: Bug > Components: Format > Reporter: Julien Le Dem > > 2 options: > - Use 64 bits for microseconds and nanoseconds, 32 bits for other units > - Use 64 bits for everything > The latter is simpler to implement, the former saves space. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
