Usage

# Minimum invocation
kafka-console-producer -topic=test -value=value -brokers=kafka1:9092

# It will pick up a KAFKA_PEERS environment variable
export KAFKA_PEERS=kafka1:9092,kafka2:9092,kafka3:9092
kafka-console-producer -topic=test -value=value

# It will read the value from stdin by using pipes
echo "hello world" | kafka-console-producer -topic=test

# Specify a key:
echo "hello world" | kafka-console-producer -topic=test -key=key

# Partitioning: by default, kafka-console-producer will partition as follows:
