No, each nginx worker keeps a persistent connection with kafka broker

/usr/local/nginx/conf # ps auxfwww | grep nginx
    1 root      0:00 nginx: master process /usr/local/nginx/sbin/nginx
    6 nobody    0:00 nginx: worker process
    7 nobody    0:00 nginx: worker process
    8 nobody    0:00 nginx: worker process
    9 nobody    0:00 nginx: worker process
   38 root      0:00 grep nginx

/usr/local/nginx/conf # netstat -t
