Mikhail Panchenko commented on KAFKA-12696: ------------------------------------------- The [contributing docs|https://cwiki.apache.org/confluence/display/KAFKA/Contributing+Code+Changes] say to assign the issue to yourself, but that does not appear possible. I do intend to provide this very simple patch :) > Add standard getters to LagInfo class to allow automatic serialization > ---------------------------------------------------------------------- > > Key: KAFKA-12696 > URL: https://issues.apache.org/jira/browse/KAFKA-12696 > Project: Kafka > Issue Type: Improvement > Components: streams > Reporter: Mikhail Panchenko > Priority: Trivial > Original Estimate: 5m > Remaining Estimate: 5m > > The LagInfo class has non-standard getters for its member variables. This > means that Jackson and other serialization frameworks do not know how to > serialize them without additional annotations. So when implementing the sort > of system that KAFKA-6144 is meant to enable, as documented here in docs like > [Kafka Streams Interactive > Queries|https://docs.confluent.io/platform/current/streams/developer-guide/interactive-queries.html#querying-state-stores-during-a-rebalance], > one has to either inject a bunch of custom serialization logic into Jersey > or wrap this class. > The patch to fix this is trivial, and I will be putting one up shortly. -- This message was sent by Atlassian Jira (v8.3.4#803005)
