------------------------------------
Summary: Arrow optimization for conversion from R DataFrame to
Spark DataFrame
Key: SPARK-25981
URL: https://issues.apache.org/jira/browse/SPARK-25981
Project: Spark
Issue Type: Improvement
Components: SparkR
Affects Versions: 3.0.0
Reporter: Hyukjin Kwon
PySpark introduced an optimization for toPandas and createDataFrame with Pandas
DataFrame.
This was leveraged by PyArrow API.
R Arrow API is under developement
(https://github.com/apache/arrow/tree/master/r) and about to be released via
CRAN (https://issues.apache.org/jira/browse/ARROW-3204).
Once it's released, we can reuse PySpark's Arrow optimization code path and
leverage it with minimised codes.
