Need help to find ELK config required for 30 lakh logs in one minute


We are having servers in our system which are going to produce around 30 lakh log lines every minute. These logs need to be inserted into ES through logstash.
We have some regex's written in logstash. Logs are pushed to logstash from filebeat.
Can someone please suggest us how many nodes/replicas/shards will be required for such a project.

Thanks in advance.

There is no way to estimate size based on the data you have provided. The best way to find out is to benchmark, and you may find the following resources useful:
