> First class partitioning support in data sources API
> ----------------------------------------------------
>
> Key: SPARK-5947
> URL: https://issues.apache.org/jira/browse/SPARK-5947
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Cheng Lian
> Assignee: Michael Armbrust
> Priority: Blocker
> Fix For: 1.4.0
>
>
> For file system based data sources, implementing Hive style partitioning
> support can be complex and error prone. To be specific, partitioning support
> include:
> # Partition discovery: Given a directory organized similar to Hive
> partitions, discover the directory structure and partitioning information
> automatically, including partition column names, data types, and values.
> # Reading from partitioned tables
> # Writing to partitioned tables
> It would be good to have first class partitioning support in the data sources
> API. For example, add a {{FileBasedScan}} trait with callbacks and default
> implementations for these features.
