[jira] [Created] (SPARK-22649) localCheckpoint support in Dataset API

Fernando Pereira created SPARK-22649:
----------------------------------------

             Summary: localCheckpoint support in Dataset API
                 Key: SPARK-22649
                 URL: https://issues.apache.org/jira/browse/SPARK-22649
             Project: Spark
          Issue Type: Improvement
          Components: PySpark, SQL
    Affects Versions: 2.2.0
            Reporter: Fernando Pereira
            Priority: Minor


localCheckpoints were recently introduced in RDDs as a way of quickly truncate the execution plan by using the caching subsystem (and therefore can not be considered reliable).

I believe it would be of major interest to offer this API in the Dataset API, and similarly in Python Dataframes.
A possible implementation is at PR19805
