Error description
The Kafka Adapter needs support for strict conversion from Avro to JSON which preserves union types in the schema, so that the produced JSON is compliant with the schema and can be converted back to Avro.
Local fix
ITXCQ - ITX00061598 LV / LV Circumvention: None
Problem summary
Users Affected: IBM Transformation Extender users using the Apache Kafka adapter. Problem Description: The adapter needed to support strict conversion from Avro to JSON which preserves union types in the schema, so that the produced JSON is compliant with the schema and can be converted back to Avro. Additionally, it was requested that the adapter provide the ability to use custom encoder and decoder classes in addition to those coming with the official Apache Avro library. Platforms Affected: All
Problem conclusion
Command -AJCM STRICT was added to the adapter to request strict conversion from Avro to JSON which preserves union types. Also -AJECN class_name and -JADCN class_name commands were added to specify custom Avro to JSON encoder class name, and custom JSON to Avro decoder class name for. For example, when -JADCN org.apache.avro.io.ExtendedJsonDecoder is specified and the avro jar provided with the adapter is replaced with community provided avro-1.9.0.12p.jar, then it is possible to produce Avro message on the topic even with the non-strict input JSON which ignores unions. Note that avro-1.9.0.12p.jar is compatible with kafka-avro-serializer-6.0.0 so 6.0.0 serializer JARs need to be combined with it. Applies to: 10.1.1.1, 10.1.2.0 Fixed in the next service packs and releases.
