-------------------------------------
Summary: Kafka Tiered Storage retry back off is not used
Key: KAFKA-17665
URL: https://issues.apache.org/jira/browse/KAFKA-17665
Project: Kafka
Issue Type: Bug
Components: core, Tiered-Storage
Reporter: Jorge Machado
Hi, we are evaluating the Kafka Tiered Storage. We already see KAFKA-17062
which under 3.9 we could have data loss. I was looking at the code and also the
KIP-405.
On the KIP it is mentioned that if a copy fails it will be retried with a
backoff propagation defined on REMOTE_LOG_MANAGER_TASK_RETRY_BACK_OFF_MS_PROP.
The issue is the method remoteLogManagerTaskRetryBackoffMs() is not used in
any place of the code. So I think this parameters make no effect currently. Is
there any retry of failed segments ? Until now I just saw logging the error.
Question from me: What happen to segments that have the state
COPY_SEGMENT_STARTED between server restarts?
