Hi,
I'm working with KAFKA_2.11-1.0.0.
I'm using the following
configuration in server.properties for LOG RETENTION POLICY:
*
log.retention.hours=168
* log.segment.bytes=1073741824
*
log.retention.check.interval.ms=300000
I'm trying to delete the kafka
topic "testTopic", by overriding the log.retention.hours properties key
using the following command:
* kafka-topics.sh --alter --zookeeper
zookeeper --topic testTopic--config retention.ms=60000
Then, i can see
the new configuration is applied for the topic 'testTopic" using the
following command:
* kafka-topics.sh --describe --zookeeper zookeeper
--topic testTopic
* Topic:testTopic PartitionCount:1
ReplicationFactor:1 Configs:retention.ms=60000
Topic: testTopic
Partition: 0 Leader: 1 Replicas: 1 Isr: 1
Once the
"log.retention.check.interval.ms" is applied by kafka (by default 5min),
my data (in kafka-logs/testTopic-0) are correctly deleted until the last
index of the topic.
But folder kafka-logs/testTopic-0 in the file
system and the topic "testTopic" in kafka UI are still present, whereas
there is no data available.
Why the folder kafka-logs is not deleted?
Is it the normal work using this configuration?
What is the best way
to delete kafka data for a topic, and finally delete the topic (to no
longer appear in kafka UI and in the file system) ?
Thanks,
