Fwd: Batching at the socket layer
I'm curious what type of batching Kafka producers do at the socket layer.

Re: Batching at the socket layer
The stickiness of partition only applies to old producer. In new producer we have the round robin for each message. The batching in new producer is per topic partition, the batch size it is controlled by both max batch size and linger time config.
