This tool creates a share group and  consumes  messages  from  a specific topic and emits share
consumer events (e.g. share consumer startup,  received  messages, and offsets acknowledged) as
JSON objects to STDOUT.

named arguments:
  -h, --help             show this help message and exit
  --topic TOPIC          Consumes messages from this topic.
  --group-id GROUP-ID    The group id of the share group
  --max-messages MAX-MESSAGES
                         Consume this many messages. If  -1  (the default), the share consumers
                         will consume until the process is killed externally (default: -1)
  --verbose              Enable to log individual consumed records (default: false)
  --acknowledgement-mode ACKNOWLEDGEMENT-MODE
                         Acknowledgement mode for the share  consumers  (must be either 'auto',
                         'sync' or 'async') (default: auto)
  --ack-pattern ACK-PATTERN
                         Comma-separated cycle of  accept|release|reject|renew  applied to each
                         consumed record via  AcknowledgeType,  selected  by  (record  offset %
                         pattern length).  RENEW  re-delivers  the  same  record,  so  its next
                         delivery advances to the following  pattern  entry instead of renewing
                         again (a pattern of only  'renew'  is  rejected,  since it could never
                         resolve). When set, the  share  consumer uses explicit acknowledgement
                         and  requires  --acknowledgement-mode   to   be   'sync'  or  'async'.
                         (default: )
  --offset-reset-strategy OFFSET-RESET-STRATEGY
                         Share group  offset  reset  strategy  (must  be  either  'earliest' or
                         'latest') (default: )
  --command-config CONFIG-FILE
                         Config properties  file  (config  options  shared  with  command  line
                         parameters will be overridden).

Connection Group:
  Group of arguments for connection to brokers

  --bootstrap-server HOST1:PORT1[,HOST2:PORT2[...]]
                         The server(s) to connect to. Comma-separated  list of Kafka brokers in
                         the form HOST1:PORT1,HOST2:PORT2,...
