alamb opened a new issue #190:
URL: https://github.com/apache/arrow-datafusion/issues/190


   *Note*: migrated from original JIRA: 
https://issues.apache.org/jira/browse/ARROW-12064
   
   The DataFrame implementation currently has two types of logic:
    # Logic for building a logical query plan
    # Logic for executing a query using the DataFusion context
   
   We can make DataFrame more extensible by having it always delegate to the 
context for execution, allowing the same DataFrame logic to be used for local 
and distributed execution.
   
   We will likely need to introduce a new ExecutionContext trait with different 
implementations for DataFusion and Ballista.
