Apache Spark reassigned SPARK-7385:
-----------------------------------
Assignee: Tathagata Das (was: Apache Spark)
> Add RDD.foreachPartitionWithIndex to allow the index to be used in
> transactions in streaming apps
> -------------------------------------------------------------------------------------------------
>
> Key: SPARK-7385
> URL: https://issues.apache.org/jira/browse/SPARK-7385
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, Streaming
> Reporter: Tathagata Das
> Assignee: Tathagata Das
>
> Spark Streaming apps often update external stores transactionally, which
> requires it to have an id that uniquely identifies the partition of data to
> be inserted. This can be the (time, partition index).
> Current work around is to use mapPartitionsWithIndex().count() which is
> awkward as it is not an action. This jira is to add
> foreachPartitionWithIndex().
