Thank you Alvaro, How to use sync producers? I am running the standard ProducerPerformance test from kafka to measure the latency of each message to send from producer to broker only. The command is like "bin/kafka-run-class.sh org.apache.kafka.clients.tools.ProducerPerformance test7 50000000 100 -1 acks=1 bootstrap.servers=esv4-hcl198.grid.linkedin.com:9092 buffer.memory=67108864 batch.size=8196"
For running producers, where should I put the producer.type=sync configuration into? The config/server.properties? Also Does this mean we are using batch size of 1? Which version of Kafka are you using? thanks.
