Hi Aeden,

`format.avro-schema` is not required anymore in the new design. The Avro schema is derived entirely from the table's schema.

Timo

Hi Timo,

Thanks for responding. You're right. So I did update the properties.
From what I can tell the new design you're referring to uses the
KafkaDynamicTableFactory, which contains the KEY_FIELDS (key.fields)
options, instead of KafkaTableSourceSinkFactoryBase, which doesn't
support those options. Is that right? So I updated my configuration to

connector    = 'kafka'
topic   = 'my-topic'
properties.group.id = 'my-consumer-group'
properties.bootstrap.servers = '...'
format = 'avro'
format.avro-schema = '....'
key.fields = 'my_key_field'

However, the property format.avro-schema doesn't appear to be
supported by KafkaDynamicTableFactory. I get this exception.

Caused by: org.apache.flink.table.api.ValidationException: Unsupported
options found for connector 'kafka'.

Unsupported options:

format.avro-schema

The format.avro-schema property was supported it what looks to me the
old design in in KafkaTableSourceSinkFactoryBase with this line,

     properties.add(FORMAT + ".*");

     
https://github.com/apache/flink/blob/master/flink-connectors/flink-connector-kafka/src/main/java/org/apache/flink/streaming/connectors/kafka/KafkaTableSourceSinkFactoryBase.java#L160

Does format.avro-schema need to be specified differently?

Thank you,
Aeden

Hi Aeden,

we updated the connector property design in 1.11 [1]. The old
translation layer exists for backwards compatibility and is indicated by
`connector.type=kafka`.

However, `connector = kafka` indicates the new property design and
`key.fields` is only available there. Please check all properties again
when upgrading, they are mentioned here [2].

Regards,
Timo

Yes, I do have that dependency. I see it in the dependency view of
intellij and directly. in the uber jar. Thanks for responding.

Hey,

have you added Kafka connector as the dependency? [1]

I've upgraded from 1.11.1 to 1.12 in hopes of using the key.fields
feature of the Kafa SQL Connector. My current connector is configured
as ,

connector.type    = 'kafka'
connector.version = 'universal'
connector.topic   = 'my-topic'
connector.properties.group.id = 'my-consumer-group'
connector.properties.bootstrap.servers = '...'
format.type = 'avro'
format.avro-schema = '....'

I tried adding

key.fields = 'my_key_field'

as well as

key.format = 'avro'
key.fields = 'my_key_field'

but I get the exception

Caused by: org.apache.flink.table.api.NoMatchingTableFactoryException:
Could not find a suitable table factory for

Reason: No factory supports all properties.

The matching candidates:
org.apache.flink.streaming.connectors.kafka.KafkaTableSourceSinkFactory

key.fields

I have validated that the uber jar clearly contains the 1.12
dependencies. What is that magic combination of properties to get
key.fields to work? Or is it not supported with avro?
