> The DataStream.write() methods rely on the {{FileSinkFunctionByMillis}} class, which has a logic for flushing records, even though the underlying stream is never flushed. This is misleading for users as files are not written as they would expect it.
> The code was initial written with FileOutputFormats in mind, but the types were not set correctly. This PR opened the write() method to any output format: https://github.com/apache/flink/pull/706/files
