[jira] [Created] (FLINK-2672) Add partitioned output format to HDFS RollingSink

-----------------------------------------------

             Summary: Add partitioned output format to HDFS RollingSink
                 Key: FLINK-2672
                 URL: https://issues.apache.org/jira/browse/FLINK-2672
             Project: Flink
          Issue Type: Improvement
          Components: Streaming Connectors
    Affects Versions: 0.10
            Reporter: Mohamed Amine ABDESSEMED
            Priority: Minor


An interesting use case of the HDFS Sink is to dispatch data into multiple directories depending of attributes present in the source data.
For example, for some data with a timestamp and a status fields, we want to write it into different directories using a pattern like : /somepath/%{timestamp}/%{status}

The expected results are somethings like:
/somepath/some_timestamp/wellformed
/somepath/some_timestamp/malformed
/somepath/some_timestamp/incomplete
...
etc

To support this functionality the bucketing and checkpointing logics need to be changed.

Note: For now, this can be done using the current version of the Rolling HDFS Sink with the help of splitting data streams and having multiple HDFS sinks.
