Matthias J. Sax commented on KAFKA-12696: ----------------------------------------- {quote}Ok. Just to confirm, the confluence where KIPs are created is a separate login, so I should sign up? {quote} Yes. Just share your account name here, and we can grant write access so you can create a KIP. Just want to clarify again: it will be difficult to get this a KIP approved, and it could easily happen that it will be rejected (just want to make sure you understand this and won't be disappointed in case it happens). > 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 > Assignee: Mikhail Panchenko > Priority: Trivial > Labels: needs-kip > Original Estimate: 0.5h > Remaining Estimate: 0.5h > > 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)
