Kenneth Knowles updated BEAM-8456:
----------------------------------
    Status: Open  (was: Triage Needed)

> BigQuery to Beam SQL timestamp has the wrong default: truncation makes the 
> most sense
> -------------------------------------------------------------------------------------

>                 Key: BEAM-8456
>                 URL: https://issues.apache.org/jira/browse/BEAM-8456
>             Project: Beam
>          Issue Type: Improvement
>          Components: dsl-sql
>            Reporter: Kenneth Knowles
>            Assignee: Kenneth Knowles
>            Priority: Major
>
> Most of the time, a user reading a timestamp from BigQuery with 
> higher-than-millisecond precision timestamps may not even realize that the 
> data source created these high precision timestamps. They are probably 
> timestamps on log entries generated by a system with higher precision.
> If they are using it with Beam SQL, which only supports millisecond 
> precision, it makes sense to "just work" by default.
