             Summary: Support non-blocking DeleteRecordsRequest
                 Key: KAFKA-20560
                 URL: https://issues.apache.org/jira/browse/KAFKA-20560
             Project: Kafka
          Issue Type: New Feature
            Reporter: Chia-Ping Tsai
            Assignee: Chia-Ping Tsai


Currently, DeleteRecords blocks until all in-sync replicas (ISR) advance the 
low watermark. This means a single slow follower can stall the request, and 
users can't distinguish the root cause from the timeout. If users set timeout=0 
to simulate a non-blocking request, the ExpiresPerSec metric will be increased 
unintentionally.
