Jerry Z created SPARK-9744: ------------------------------ Summary: Add RDD method to map with lag and lead Key: SPARK-9744 URL: https://issues.apache.org/jira/browse/SPARK-9744 Project: Spark Issue Type: Wish Reporter: Jerry Z
To avoid zipping with index and doing numerous mapping and joins, having a single method call to map with an additional two parameters (1: list of offsets [(-) for lag, 0 for current and (+) for lead])) and (2:default value). The other difference to the map function takes an argument of List<T> and not just T. -- 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
