Hyukjin Kwon created SPARK-11687: ------------------------------------ Summary: Mixed usage of fold and foldLeft, reduce and reduceLeft and reduceOption and reduceLeftOption Key: SPARK-11687 URL: https://issues.apache.org/jira/browse/SPARK-11687 Project: Spark Issue Type: Improvement Reporter: Hyukjin Kwon Priority: Trivial
As can be seen here https://github.com/scala/scala/blob/2.12.x/src/library/scala/collection/TraversableOnce.scala, fold, reduce and reduceOption came out from scala 2.9.x. In addition, all the implementations of fold, reduce and reduceOption call actually foldLeft, reduceLeft and reduceLeftOption directly without any additional codes. For developers who is not really used to scala, the mixed usage of them might leave a question. Even some usages can be found where they work identically the same things. This is just a little nit but I think it would be better to use only xxxLeft for readability. -- 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
