Wenchen Fan reassigned SPARK-31398: ----------------------------------- Assignee: Maxim Gekk > Speed up reading dates in ORC > ----------------------------- > > Key: SPARK-31398 > URL: https://issues.apache.org/jira/browse/SPARK-31398 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.0.0 > Reporter: Maxim Gekk > Assignee: Maxim Gekk > Priority: Major > > Currently, ORC datasource converts values of DATE type to java.sql.Date and > the result to days since the epoch in Proleptic Gregorian calendar. ORC > datasource does such conversion when > spark.sql.orc.enableVectorizedReader is set to false. > The conversion to java.sql.Date is not necessary because we can use > DaysWritable which performs rebasing in much more optimal way. -- 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
