Sharing Kafka producer between threads

Question

Is it possible to have single instance of a Kafka producer shared between multiple threads to send messages to multiple topics? Is there any concurrency issue I might want to be aware of before?

According to the KafkaProducer documentation

The producer is thread safe and sharing a single producer instance across threads will generally be faster than having multiple instances.

So yes, it's perfectly valid and even recommended to share a single producer between multiple threads.

If I am pushing data from database to Kafka Producer to two different topics, how to achieve sending messages from same database simultaneously to two different topics ? – preetham Jan 09 '18 at 00:17
by invoking send for two times i guess. – Mikita Harbacheuski Jan 09 '18 at 10:25
