Martin Senne updated SPARK-10868:
---------------------------------
Description:
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*.
**Background and justification**:
Additional row for a DataFrame that is written to a DB (via .jdbc).
In detail:
- A DataFrame A (containing an ID column) and having indices from 0 to 199 in
that column.
