Maxim Gekk created SPARK-31579: ---------------------------------- Summary: Replace floorDiv by / in localRebaseGregorianToJulianDays() Key: SPARK-31579 URL: https://issues.apache.org/jira/browse/SPARK-31579 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 3.1.0 Reporter: Maxim Gekk
Most likely utcCal.getTimeInMillis % MILLIS_PER_DAY == 0 but need to check that for all available time zones in the range of [0001, 2100] years with the step of 1 hour or maybe smaller. If this hypothesis is confirmed, floorDiv can be replaced by /, and this should improve performance of RebaseDateTime.localRebaseGregorianToJulianDays. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
