question about console producer behavior

[raymond <rg...@gmail.com>]

Hi

It appears to me that, when I have opened a console producer, it will not notice the topic’s partition change?

say I have a topic with 3 partitions. And I opened a console producer to produce data with key, then it will distribute data into 3 partitions. Then , I keep this producer open, and change the topic’s partition to e.g. 4. This producer will not distribute data into the 4th partition, while a newly created producer will.

Is this behavior expected?

Hi,

Producers will only refresh their metadata periodically if there is no
exceptions caught sending the data, you can config this period in "
topic.metadata.refresh.interval.ms" (default is 600 seconds).
