----------------------------------
Summary: Disk space is not released after Kafka clears data due to
retention settings
Key: KAFKA-9371
URL: https://issues.apache.org/jira/browse/KAFKA-9371
Project: Kafka
Issue Type: Bug
Components: core, streams
Affects Versions: 2.2.0
Environment: CentOS 7.7
Reporter: Arda Savran
We defined retention time on topics for 15 minutes. It looks like Kafka is
deleting the messages as configured however the disk space is not restored.
"df" output shows 30G for kafka-logs instead of the real size which is supposed
to be 1Gb.
{{/usr/sbin/lsof | grep deleted }}
output shows a bunch of files under kafka-logs that are deleted but they are
still consuming space.
Is this a known issue? Is there a setting that I can apply to kafka broker
server?
