Michael Armbrust updated SPARK-15380: ------------------------------------- Target Version/s: 2.3.0 (was: 2.2.0) > Generate code that stores a float/double value in each column from > ColumnarBatch when DataFrame.cache() is used > --------------------------------------------------------------------------------------------------------------- > > Key: SPARK-15380 > URL: https://issues.apache.org/jira/browse/SPARK-15380 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Kazuaki Ishizaki > > When DataFrame.cache() is called, data will be stored as column-oriented > storage in CachedBatch. The current Catalyst generates Java program to store > a computed value to an InternalRow and then the value is stored into > CachedBatch even if data is read from ColumnarBatch for ParquetReader. > This JIRA generates Java code to store a value into a ColumnarBatch, and > store data from the ColumnarBatch to the CachedBatch. This JIRA handles only > float and double types for a value. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
