So when I look for a way to count the messages in a topic, this one is good
kafka-run-class kafka.tools.GetOffsetShell --broker-list broker1:9092,broker2:9092,broker3:9092 --topic rev-dly-upd --time -1
The only thing is, when I change the retention.ms
config to retention.ms=1000
, and even check that the topic has been configured by running kafka-topics --describe --zookeeper zookeeper1:2181 --topic rev-dly-upd
. I can see clearly that that config is set at 1000...
Topic:rev-dly-upd PartitionCount:8 ReplicationFactor:3 Configs:retention.ms=1000
Topic: rev-dly-upd Partition: 0 Leader: 159 Replicas: 159,96,160 Isr: 159,96,160
Topic: rev-dly-upd Partition: 1 Leader: 160 Replicas: 160,159,94 Isr: 94,160,159
Topic: rev-dly-upd Partition: 2 Leader: 94 Replicas: 94,160,95 Isr: 95,94,160
Topic: rev-dly-upd Partition: 3 Leader: 95 Replicas: 95,94,96 Isr: 95,96,94
Topic: rev-dly-upd Partition: 4 Leader: 96 Replicas: 96,95,159 Isr: 95,96,159
Topic: rev-dly-upd Partition: 5 Leader: 159 Replicas: 159,160,94 Isr: 159,94,160
Topic: rev-dly-upd Partition: 6 Leader: 160 Replicas: 160,94,95 Isr: 94,160,95
Topic: rev-dly-upd Partition: 7 Leader: 94 Replicas: 94,95,96 Isr: 95,96,94
yet when I run kafka-run-class kafka.tools.GetOffsetShell --broker-list broker1:9092,broker2:9092,broker3:9092 --topic rev-dly-upd --time -1
all I always get records returned. What could the reasons be?
