Subject [DISCUSS] KIP-232: Detect outdated metadata by adding ControllerMetadataEpoch field
Date Sat, 02 Dec 2017 02:33:05 GMT
Hi all,

I have created KIP-232: Detect outdated metadata by adding
ControllerMetadataEpoch field:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-232%3A+Detect+outdated+metadata+by+adding+ControllerMetadataEpoch+field
.

The KIP proposes to add fields in MetadataResponse and
UpdateMetadataRequest so that client can reject outdated metadata and avoid
unnecessary OffsetOutOfRangeException. Otherwise there is currently race
condition that can cause consumer to reset offset which negatively affect
the consumer's availability.

Feedback and suggestions are welcome!

Regards,
Dong
