$ fission fn create --help
Create a function (and optionally, an HTTP route to it)

Options:
  --concurrency=500 (--con)             Maximum number of pods specialized concurrently to serve
                                        requests (Only valid for executortype; `poolmgr`)
  --requestsperpod=1 (--rpp)            Maximum number of concurrent requests that can be served by a
                                        specialized pod (Only valid for executortype; `poolmgr`)
  --onceonly=false (--yolo)             Specifies if specialized pod will serve exactly one request in
                                        its lifetime (Only valid for executortype; `poolmgr`)
