> File sources (such as {{ExecutionEnvironment#readCsvFile()}}) and sinks (such as {{FileOutputFormat}} and its subclasses, and methods such as {{DataSet#writeAsText()}}) need the ability to transparently decompress and compress files. Primarily gzip would be useful, but it would be nice if this were pluggable to support bzip2, xz, etc.
> There could be options for autodetect (based on file extension and/or file content), which could be the default, as well as no compression or a selected compression method.
