[jira] [Created] (FLINK-9560) RateLimiting for FileSystem

Etienne CARRIERE created FLINK-9560:

             Summary: RateLimiting for FileSystem
                 Key: FLINK-9560
             Project: Flink
          Issue Type: Improvement
          Components: FileSystem
    Affects Versions: 1.5.0
            Reporter: Etienne CARRIERE

*Pain*: On our system, we see that during checkpoint , all the bandwidth is take to send the checkpoint to object storage (s3 in our case)

*Proposal* : After the creation of some limitation on Filesystem (mostly number of connections with the  tickets FLINK-8125/FLINK-8198/FLINK-9468), I propose to add ratelimiting "per Filesystem" .

Proposal of implementation : Modify LimitedConnectionsFileSystem to add a ratelimiter on both Input and OutputStream.

Current issue : I would like to use the guava RateLimiter that is a good ratelimiter but it is guava and so not included in flink (dependency clash with hadoop) if I am right. What would be a right strategy in this case ?
