--------------------------------------
Hello [~martijnvisser]
Is this PR enough for this issue? Can I help with something to make it go
through easier?
> The confluent schema registry is not compatible with Apicurio schema registry
> -----------------------------------------------------------------------------
>
> Key: FLINK-30721
> URL: https://issues.apache.org/jira/browse/FLINK-30721
> Project: Flink
> Issue Type: Bug
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
> Reporter: Pedro Mázala
> Priority: Major
> Labels: pull-request-available
>
> With the format `avro-confluent`, it is impossible to use
> [Apicurio|https://www.apicur.io/].
> [The
> code|https://github.com/apache/flink/blob/master/flink-formats/flink-avro-confluent-registry/src/main/java/org/apache/flink/formats/avro/registry/confluent/ConfluentSchemaRegistryCoder.java#L71]
> reads a 4-byte integer (see `readInt` documentation
> [here|https://docs.oracle.com/javase/7/docs/api/java/io/DataInput.html#readInt()])
> and Apicurio stores its schema ids as a long ([8
> bytes|https://docs.oracle.com/javase/7/docs/api/java/io/DataInput.html#readLong()]).
> The solution could be adding the schema size to be read from the log message.
