How is that about that when the segment size is reached, plus every single message inside the segment is older than the retention time, then the segment will be deleted?
I have playing with Kafka and I have the following: bin/kafka-topics.sh --zookeeper localhost:2181 --alter --topic topic1 config retention.ms=60000 bin/kafka-topics.sh --zookeeper localhost:2181 --alter --topic topic1 —config file.delete.delay.ms=40000 bin/kafka-topics.sh --zookeeper localhost:2181 --alter --topic topic1 --config segment.bytes=400000 My understanding according to your thoughts is a segment will be deleted when the segment reaches out the segment size above defined (segment.bytes=400000) PLUS every single message within the segment is older than the retention time above defined (retention.ms=60000). What I noticed is a segment of just 35 bytes, which conteined just one message, was deleted after the minute (maybe a little more). Therefore, the segment size was not met in order to delete it.
