[jira] [Created] (SPARK-12931) Improve bucket read path to only create one single RDD

Wenchen Fan created SPARK-12931:
-----------------------------------

             Summary: Improve bucket read path to only create one single RDD
                 Key: SPARK-12931
                 URL: https://issues.apache.org/jira/browse/SPARK-12931
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Wenchen Fan


Currently we will create one RDD per bucket and coalesce it to one partition, and finally union them to a final RDD. We should create a single RDD instead, it requires to modify the data source interface a little bit and abstract the logic of reader out to decouple it from RDD.
