[jira] [Created] (KAFKA-12981) Ensure LogSegment.maxTimestampSoFar
and LogSegment.offsetOfMaxTimestampSoFar are read/updated in sync
Tom Scott created KAFKA-12981:
---------------------------------
Summary: Ensure LogSegment.maxTimestampSoFar and LogSegment.offsetOfMaxTimestampSoFar are read/updated in sync
Key: KAFKA-12981
URL: https://issues.apache.org/jira/browse/KAFKA-12981
Project: Kafka
Issue Type: Sub-task
Reporter: Tom Scott
KIP-734 extends listOffsetRequest to fetch offsets by max timestamp as well as by start and end offset. This relies on LogSegment.maxTimestampSoFar and LogSegment.offsetOfMaxTimestampSoFar but there is currently no synchronisation between the 2 meaning that one could be updated whilst the other is being read.
This ticket ensure that LogSegment.maxTimestampSoFar and LogSegment.offsetOfMaxTimestampSoFar are locked on read to ensure synchronisation.
