Sandy Ryza commented on SPARK-5097:
-----------------------------------
Ah, yeah, I hadn't considered that aspect. I definitely agree that making them
column-mutable would be very ugly. I'd push for add_column over addColumn, but
maybe the ship with those naming conventions on it has already sailed.
> Adding data frame APIs to SchemaRDD

> Key: SPARK-5097
> URL: https://issues.apache.org/jira/browse/SPARK-5097
> Project: Spark
> Issue Type: Sub-task
> Components: SQL

>
> SchemaRDD, through its DSL, already provides common data frame
> functionalities. However, the DSL was originally created for constructing
> test cases without much end-user usability and API stability consideration.
> This design doc proposes a set of API changes for Scala and Python to make
> the SchemaRDD DSL API more usable and stable.
