The following configuration is now possible

  ## CompressionCodec represents the various compression codecs recognized by Kafka in messages.
  ##  0 : No compression
  ##  1 : Gzip compression
  ##  2 : Snappy compression
  compression_codec = 0

  ##  RequiredAcks is used in Produce Requests to tell the broker how many replica acknowledgements it must see before responding
  ##  0 : the producer never waits for an acknowledgement from the broker. This option provides the lowest latency but the weakest durability guarantees (some data will be lost when a server fails).
  ##  1 : the producer gets an acknowledgement after the leader replica has received the data. This option provides better durability as the client waits until the server acknowledges the request as successful (only messages that were written to the now-dead leader but not yet replicated will be lost).
  ##  -1 : the producer gets an acknowledgement after all in-sync replicas have received the data. This option provides the best durability, we guarantee that no messages will be lost as long as at least one in sync replica remains.
  required_acks = -1

  ##  The total number of times to retry sending a message
  max_retry = 3
