[jira] [Comment Edited] (SPARK-19256) Hive bucketing support
[ https://issues.apache.org/jira/browse/SPARK-19256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16345397#comment-16345397 ]

------------------------------------------------------------------
Thanks a lot for this great contribution to Spark.
I was just wondering, would it make sense to apply this to direct outputs (e.g. write.parquet()), so that we could keep partitioning information - and again avoid reshuffling data before a merge? I believe this is most what saveAsTable() does by default in Spark, but to my mind it would improve the DataFrame write API and make these performance benefits more accessible.
Update:
I've just noticed that it has been considered in [https://github.com/apache/spark/pull/13452.
] [~cloud_fan] [ |https://github.com/apache/spark/pull/13452.]- Is there an Issue to follow up on this feature? Eventually we could simply store a metadata json file together with the data files.
