If the logstash restarts, how to ensure that the read kafka offset begins the last one befor reboot, 'auto\_offset\_reset' just supports earliest / lastest, which may cause the data to read missing or duplicate, the old version setting 'zk\_connect', and should be able to keep the offset on zookeeper , The new version 'bootstrap\_servers' , did not consider offset maintenance? -- From google translation
