----------------------------------
Summary: Better document what LogAppendTime means
Key: KAFKA-5718
URL: https://issues.apache.org/jira/browse/KAFKA-5718
Project: Kafka
Issue Type: Improvement
Components: documentation
Affects Versions: 0.11.0.0
Reporter: Dustin Cote
Priority: Trivial
There isn't a good description of LogAppendTime in the documentation. It would
be nice to add this in somewhere to say something like:
LogAppendTime is some time between when the partition leader receives the
request and before it writes it to it's local log.
There are two important distinctions that trip people up:
1) This timestamp is not when the consumer could have first consumed the
message. This instead requires min.insync.replicas to have been satisfied.
2) This is not precisely when the leader wrote to it's log, there can be delays
along the path between receiving the request and writing to the log.
