Usage: bench_reqrep.py [OPTIONS] CFG_FROM [CFG_TO]

  Copy from one objstorage to the other. This tool is dedicated to
  stress testing swh-objstorage backends.

  The obj storages arguments can be given a either a file name (the
  standard obj storage config file in yaml) or as an url of the form:

      <backend>://?<arg>=<value>&[...]

  If this url is a standard http one, it is expected to be the url of a
  running swh objstorage server.

  If the destination obj storage is not given, objects are dropped (for
  a read only stress test).

  It will produce simple performance summary as output, but is will
  also push statsd metrics on the UDP endpoint given by the
  STATDS_HOST/STATSD_PORT environment variable (these default to
  localhost:8125), if you want to see real time curves of how the copy
  is performing.

  Examples:

  - Generate random objects and put them in a running objstorage
  listening on   port 5003:

    swh-objstorage-copy random:// http://127.0.0.1:5003

  - Same as above, but limit the generator to 1000 fixed size objects:

    swh-objstorage-copy random://?total=1000&filesize=1024
    http://127.0.0.1:5003

  - Pull with 16 workers x 2 threads from a local pathslicer only for
  2mn:

    swh-objstorage-copy -t 120 -w 16 -c 2
    pathslicing://?root=/tmp/objstorage&slicing=0:4/8:10
