--------------------------------------
Summary: LogCleaner should be transaction-aware
Key: KAFKA-5196
URL: https://issues.apache.org/jira/browse/KAFKA-5196
Project: Kafka
Issue Type: Sub-task
Reporter: Jason Gustafson
Assignee: Jason Gustafson
Priority: Critical
Fix For: 0.11.0.0
In accordance with the KIP-98 design, the log cleaner should be aware of
transaction markers. This means the following:
1. Cleaning should be restricted below the last stable offset (which ensures
that only decided data is considered when cleaning).
2. Records from aborted transactions are removed immediately.
3. Removal of the COMMIT/ABORT markers must be delayed to ensure that they are
not missed by concurrent readers.
