> 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
> Priority: Major
>
> BucketingSink creates files with the following pattern
> {noformat}
> partPrefix + "-" + subtaskIndex + "-" + bucketState.partCounter{noformat}
> When using checkpointing you have no control over the extension of the final
> 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 unless you set a special property. See [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
