--------------------------------------------
Summary: Introduce delayed remote list offsets to make
LIST_OFFSETS async
Key: KAFKA-15859
URL: https://issues.apache.org/jira/browse/KAFKA-15859
Project: Kafka
Issue Type: Task
Reporter: Kamal Chandraprakash
Assignee: Kamal Chandraprakash
LIST_OFFSETS API request is handled by the request handler threads. If there
are concurrent LIST_OFFSETS requests to remote storage more than the number of
request handler threads, then other requests such as FETCH and PRODUCE might
starve and be queued. This can lead to higher latency in producing/consuming
messages.
The `offsetForTimes` call to remote storage can take time as it has to fetch
the offset and time indexes to serve the request so moving the requests to
purgatory and handle it via the remote-log-reader threads frees up the request
handler threads to serve other requests.
