Gunnar Morling commented on KAFKA-3832: --------------------------------------- What would be the right fix to this issue then, could it simply be changed to return a null value in this case? That should be simple enough, but I'm wondering whether there'll be a problem if some records have a schema (non-tombstones) and some others don't (tombstones). > Kafka Connect's JSON Converter never outputs a null value > --------------------------------------------------------- > > Key: KAFKA-3832 > URL: https://issues.apache.org/jira/browse/KAFKA-3832 > Project: Kafka > Issue Type: Bug > Components: KafkaConnect > Affects Versions: 0.9.0.1 > Reporter: Randall Hauch > Assignee: Prasanna Subburaj > Priority: Major > Labels: newbie > > Kafka Connect's JSON Converter will never output a null value when > {{enableSchemas=true}}. This means that when a connector outputs a > {{SourceRecord}} with a null value, the JSON Converter will always produce a > message value with: > {code:javascript} > { > "schema": null, > "payload": null > } > {code} > And, this means that while Kafka log compaction will always be able to remove > earlier messages with the same key, log compaction will never remove _all_ of > the messages with the same key. > The JSON Connector's {{fromConnectData(...)}} should always return null when > it is supplied a null value. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
