We are creating new producer connections each time but in separate threads(pool of 40 and all threads will be used most of the time) and closing it when work in done. its a java process.

Not always but sometimes close connection takes more than 10 seconds and observerd that particular message was never published.

Could you please help.

 

{{Properties prop = new Properties(); }}

{{prop.put("bootstarp.servers",-);}}

{{prop.put("acks","all"); }}

{{//some ssl properties }}

{{--- }}

{{//ends KafkaProducer }}

{{connection = null; }}

{{try { }}

{{connection = new KafkaProducer<String, byte[]>(props); msg.setTopic(topic); }}

{{msg.setDate(new Date());}}

{{ connection.send(msg);}}

{{ } catch() {}}

{{ } finally { }}

{{connection.close();// sometimes it takes more than 10 secs and the above message was not send }}

{{}}}

Producer config :

max.in.flight.requests.per.connection = 5

acks= all

batch.size = 16384

linger.ms = 0

max.block.ms = 60000

request.timeout.ms = 5000
