Michael Lorenzi created FLINK-33045:
---------------------------------------
Summary: format avro-confluent - disable auto-registering schema
in registry
Key: FLINK-33045
URL: https://issues.apache.org/jira/browse/FLINK-33045
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Affects Versions: 1.17.1
Environment: Flink-Kubernetes-Operator
format avro-confluent
Reporter: Michael Lorenzi
{code:java}
'value.format' = 'avro-confluent',
'value.avro-confluent.url' = '<url>',
'value.avro-confluent.schema' = '<schema>', -- available in 1.18.x{code}
Currently the format {{avro-confluent}} seems to always try to register the
schema to the schema-registry, be it computed out of the table-schema or set by
property {{schema}} (if 1.18.x is used).
In our setup we would like to prevent our flink-jobs from registering schemas.
Flink should only lookup the schema-id by calling {{getId}} from confluents
schema-registry-client. We control publishing of new schema-versions outside of
flink.
The bevaviour is expected to be similar to the behvaiour of KafkaAvroSerializer
from confluent when {{auto.register.schemas=false}} is set.
Could there be a option like
{code:java}
'value.avro-confluent.auto-register.schema' = 'false'{code}
to disable auto-registering schema to the schema-registry?
Thank you for your help!
