             Summary: Allow compression of row format files created by 
StreamingFileSink
                 Key: FLINK-11794
                 URL: https://issues.apache.org/jira/browse/FLINK-11794
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / FileSystem
    Affects Versions: 1.7.2
            Reporter: Elias Levy


Currently, there is no mechanism to compress files created using a 
StreamingFileSink.  This is highly desirable when output is a text based row 
format such as JSON.

Possible alternatives are the introduction of a callback that gets passed the 
local file before it is uploaded to the DFS, so that it could be compressed; or 
a factory method could be used that returns an OutputStream, such as 
GZIPOutputStream, that compresses a passed in output stream that could be then 
used by the Encoder.
