Resolution: Fixed
> Cache timezone name look ups
> ----------------------------
>
> Key: IMPALA-7086
> URL: https://issues.apache.org/jira/browse/IMPALA-7086
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Csaba Ringhofer
> Assignee: Mihaly Szjatinya
> Priority: Major
> Labels: performance, ramp-up, timestamp
>
> to/from_utc_timestamp looks up time zones by name during every invocation,
> even if the timezone parameter is constant. Avoiding this lookup if time zone
> name is the same as during the last call (in the fragment) could speed up
> time zone conversions.
