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

             Summary: Control over the extension of part files created by BucketingSink
                 Key: FLINK-8814
                 URL: https://issues.apache.org/jira/browse/FLINK-8814
             Project: Flink
          Issue Type: Improvement
          Components: Streaming Connectors
    Affects Versions: 1.4.0
            Reporter: Jelmer Kuperus


BucketingSink creates files with the following pattern
{noformat}
partPrefix + "-" + subtaskIndex + "-" + bucketState.partCounter{noformat}
You have no control over the extension of the files generated. This is incovenient when you are for instance writing files in the avro format because


 # [Hue|http://gethue.com/] will not be able to render the files as avro See this [file|https://github.com/cloudera/hue/blob/master/apps/filebrowser/src/filebrowser/views.py#L730]
 # [Spark avro|https://github.com/databricks/spark-avro/] will not be able to read the files. See for instance [this ticket|https://github.com/databricks/spark-avro/issues/203]

It would be good if we had the ability to customize the extension of the files created
