How many TCP connections Java producers opens to feed data to broker?

Hello,

does it use just one connection to one broker? One connection to each
broker? Or opens multiple connection to one broker to achieve higher
throughput?

 

Many thanks,

Petr

One connection to each broker. You can get very high throughput even with a
single TCP connection. The producer handles batching internally so you
don't send small requests if you have high data rates.
