Hello, I am using a Kafka with version 0.11.xx. When I check the logs I can see the index segments for user defined topics are getting deleted. But I cannot find the indices for the consumer_offset topic getting deleted. That's causing around GBs of data getting accumulated in our persistent disk. Based on the server.properties file,we haven't set any offsets.retention.minutes. So I am assuming the default values would be used which is 24 hours. But still I can find .index files in the __consumer_offsets topic which are months old. Cannot you guys tell me what could be the reason for this. Also a workaround to fix this issue would help too.
Any kind of help is greatly appreciated. Regards, Kaushik Nambiar
