Kazuaki Ishizaki commented on SPARK-14098: ------------------------------------------ After fixing some trivial compilation failures, I will create a PR as WIP soon. > Generate code that get a 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 > Reporter: Kazuaki Ishizaki > > When DataFrame.cache() is called, data is stored as column-oriented storage > in CachedBatch. In some cases, data is compressed. > 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. -- 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
