We have configured logstash(using default pipeline configuration). We have just one pipeline running.
When I start logstash I see it has 4 pipeline workers and batch size of 125. I am using IMAP input plugin to process emails from server.
I see that all 4 workers establish connection with IMAP.
I want to know if all workers connect to IMAP endpoint, do all workers operate parallel or just 1 worker communicates?
Thanks in advance for your help.
