--------------------------------------
Summary: Use cached hw/lso offset metadata when reading from log
Key: KAFKA-8717
URL: https://issues.apache.org/jira/browse/KAFKA-8717
Project: Kafka
Issue Type: Improvement
Reporter: Jason Gustafson
Assignee: Jason Gustafson
The broker caches log offset metadata (e.g. segment position) for the high
watermark and last stable offset in order to avoid additional index lookups
when handling fetches. Currently this metadata is only used when determining
delayed fetch satisfaction. We can also use it when reading from the log in
order to avoid additional redundant index lookups.
