Understand "reconnect" and "retries" settings in Kafka output

Elastic Stack Logstash
3

Hello Wolfram,

Thansk for this feedback

I'm not sure to understand because, when you look at the logs above, reconnect happen evey 50 ms and never increase exponentially :

I we take only kakfa 2 :

ff

I speak about reconnect_backoff setting Kafka output plugin | Logstash Reference [7.12] | Elastic

Or maybe Logstash setting is just static and not exponential ?
