[jira] [Created] (FLINK-19339) Support Avro's unions with logical
types
Dawid Wysakowicz created FLINK-19339:
----------------------------------------
Summary: Support Avro's unions with logical types
Key: FLINK-19339
URL: https://issues.apache.org/jira/browse/FLINK-19339
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Reporter: Dawid Wysakowicz
Assignee: Dawid Wysakowicz
Fix For: 1.12.0
Avro 1.9.x introduced yet another mechanism for registering/looking up conversions for logical types. See https://issues.apache.org/jira/browse/AVRO-1891
If a logical type is part of a union a static field {{MODEL$}} of type {{SpecificData}} will be added to the generated Avro class with registered conversions for a logical type. We should use that {{SpecificData}} in {{AvroSerializer}} and {{Avro(De)SerializationSchema}} whenever available.
