[jira] [Updated] (SPARK-26924) Document Arrow optimization and
vectorized R APIs
[ https://issues.apache.org/jira/browse/SPARK-26924?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hyukjin Kwon updated SPARK-26924:
---------------------------------
Description:
Arrow optimization was added but Arrow is not available on CRAN.
So, it had to add some hacks to avoid CRAN check in SparkR side. For example, see
https://github.com/apache/spark/search?q=requireNamespace1&unscoped_q=requireNamespace1
These should be removed to properly check CRAN in SparkR
See also ARROW-3204
was:We should update SparkR guide documentation, and some related documents, comments like in {{SQLConf.scala}} when most of tasks are finished.
