Luke Hutchison updated FLINK-6185:
----------------------------------
Description:
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.
