-----------------------------------------------------------
[~jangbora] looking at the metrics above, they represent per client-id quota
metrics. Inactive quota metrics will be deleted after one hour. looks like you
are creating many producer instances within an hour. As mentioned [~huxi_2b],
You can use single producer instance across multiple threads. (or) you can
reuse client.id string (or) if you are not using quotas, you can disable quota
configs.
Please close the JIRA, if you satisfy with one of the above approaches.
