-------------------------------------
Hi [[email protected]],
I am not aware of any way to remove Producer metrics tbh. Just had a quick look
(2 minutes) at the code and couldn't find anything either.
If this is a problem for you, it would probably be best to periodically
reinitialize your producers, how that would best be done depends heavily on how
you use them though. Using a 1:1 assignment of producer to topic is one option
- if it is a sensible one depends again on your setup though.
> Memory Leak in Kafka Producer
> -----------------------------
>
> Key: KAFKA-9609
> URL: https://issues.apache.org/jira/browse/KAFKA-9609
> Project: Kafka
> Issue Type: Bug
> Components: clients, producer
> Affects Versions: 2.4.0
> Reporter: Satish
> Priority: Major
>
> org.apache.kafka.clients.producer.internals.Sender adds Topic Metrics for
> every topic that we are writing messages to but it never been cleaned up
> until we close the producer.
> This is an issue if we use single producer and have more number of Dynamic
> topics (eg: ~ 500 topics per hour) and writing messages to them. As this
> Metrics map is getting accumulated for every topic, over a period of time we
> notice the memory usage gets increased gradually.
> It can be easily reproducible by writing messages to the more # of dynamic
> topics using the same KafkaProducer from apache kafka client libraries or
> KafkaTemplate from Spring.
