-------------------------------------
Summary: Remove String Manipulation from Date Parsing
TimestampTZUtil
Key: HIVE-24701
URL: https://issues.apache.org/jira/browse/HIVE-24701
Project: Hive
Issue Type: Improvement
Reporter: David Mollitor
Assignee: David Mollitor
This operation is pretty slow:
{code:java}
// Converts Date to TimestampTZ.
public static TimestampTZ convert(Date date, ZoneId defaultTimeZone) {
return parse(date.toString(), defaultTimeZone);
}
{code}
To convert from Date to TimestampTZ, it creates a string, then parses it.
Should be able to just look at the epoch time and do the conversion without all
the string manipulation/parsing.
