Elasticsearch output workers for logstash 5.1

[rpuserh (Ruben Papovyan)]

Hi,
I want to open multiple connection to elastcsearch
I used before workers => num
but now it giving error.

I found in documentation this

workers
Value type is string
Default value is 1
Output workers are no longer supported. Please use plugin workers

but i didn't found any plugin workers.

So please help me on this, provide documentation uri or config example
