[jira] [Created] (SPARK-10868) monotonicallyIncreasingId() supports offset to start indexing at

Martin Senne created SPARK-10868:
------------------------------------

             Summary: monotonicallyIncreasingId() supports offset to start indexing at
                 Key: SPARK-10868
                 URL: https://issues.apache.org/jira/browse/SPARK-10868
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 1.5.0
            Reporter: Martin Senne


With SPARK-7135 and https://github.com/apache/spark/pull/5709 `monotonicallyIncreasingID()` allows to create an index column with unique ids. The indexing always starts at 0 (no offset).

Feature wish: Having a parameter `offset`, such that the function can be used as

    monotonicallyIncreasingID( offset )

and indexing starts at `offset` instead of 0.
