Shuai Lin commented on SPARK-14098: ----------------------------------- [~kiszk] Seems the title/description of this ticket is not on par with what is done in https://github.com/apache/spark/pull/15219 . Should we update the title/description here? > Generate code that get a float/double value in each column from CachedBatch > when DataFrame.cache() is called > ------------------------------------------------------------------------------------------------------------ > > Key: SPARK-14098 > URL: https://issues.apache.org/jira/browse/SPARK-14098 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Kazuaki Ishizaki > > When DataFrame.cache() is called, data is stored as column-oriented storage > in CachedBatch. The current Catalyst generates Java program to get a value of > a column from an InternalRow that is translated from CachedBatch. This issue > generates Java code to get a value of a column from CachedBatch. While a > column for a cache may be compressed, this issue handles float and double > types that are never compressed. > Other primitive types, whose column may be compressed, will be addressed in > another entry. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
