Mickael Maison commented on KAFKA-6633:
---------------------------------------
Yes it is still the case. And it's also still in the javadoc !
See
[http://kafka.apache.org/10/javadoc/index.html?org/apache/kafka/clients/producer/KafkaProducer.html]
or
[https://github.com/apache/kafka/blob/1.0.1/clients/src/main/java/org/apache/kafka/clients/producer/KafkaProducer.java#L85-L86|https://github.com/apache/kafka/blob/1.0.1/clients/src/main/java/org/apache/kafka/clients/producer/KafkaProducer.java#L85-L86]
It's right at the top:
{code:java}
The producer is thread safe and sharing a single producer instance across
threads will generally be faster than having multiple instances. {code}
> Is KafkaProducer still thread safe in version 1.0.1
> ---------------------------------------------------

> Key: KAFKA-6633
> URL: https://issues.apache.org/jira/browse/KAFKA-6633
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 1.0.1
> Reporter: Herbert Koelman
> Priority: Minor
>
> The javadoc of version
> [0.8|https://kafka.apache.org/082/javadoc/org/apache/kafka/clients/producer/KafkaProducer.html]
> states that producers are thread safe:
> {quote}{{The producer is _thread safe_ and should generally be shared among
> all threads for best performance.}}
> {quote}
> Is it still the case in version 1.0.1 ? I failed to find this information in
> the javadoc of version 1.0.1.
> Can I share one producer with many threads ?
> (I posted this question as a bug, because I didn't know where else I could
> post questions. Sorry)
