----------------------------------
Summary: Make Rowdata converters public
Key: FLINK-19098
URL: https://issues.apache.org/jira/browse/FLINK-19098
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table
SQL / Ecosystem
Affects Versions: 1.11.0
Reporter: Brian Zhou
Some of the Rowdata converters(SeDer between Rowdata and format objects like
GenericRecord/JsonNode) are private or package-private (like Json), this is not
easy for other third-party connector projects to utilize to implement its own
format factory in Table API.
For example, Pravega connector is now developing a schema-registry-based format
factory. The [Pravega schema
registry|https://github.com/pravega/schema-registry] is a rest service similar
with confluent registry , but it can help to serialize/deserialize
json/avro/protobuf/custom format data. It will help a lot if these converters
are public.
Noticed in FLINK-16048, we have already moved the avro converters out and made
them public. Similarly, it should be safe to make at least json and csv format
converters public.
