How to purge Kafka Topic

0 votes

I want to push a message into a kafka topic on my local machine.

But every time I'm trying to do it, I'm getting an error:

kafka.common.InvalidMessageSizeException: invalid message size
Increasing the fetch.size is not ideal here, because I don't actually want to accept messages that big. 

Is there a way to purge the topic in kafka?

Thanks in advance!

For your case what you can do is, temporarily update the retention time on the topic to one second:

kafka-topics.sh --zookeeper localhost:2081 --alter --topic DemoTopic --config retention.ms=1000
then wait for the purge to take effect (about one minute). Once purged, restore the previous retention.ms value.

Hope this will help.
