Jark Wu commented on FLINK-19517:
---------------------------------
Hi [~ksp0422],
1) It is determined whether it is used as source or sink. If it is used as
sink, e.g. {{INSERT INTO kafka}}, then the properties will be used for
producer.
2) Yes. Flink SQL Client doesn't support gateway mode natively.
flink-sql-gateway is a project based on Flink SQL which can support REST API
call.
> Support for Confluent Kafka of Table Creation in Flink SQL Client
> -----------------------------------------------------------------
>
> Key: FLINK-19517
> URL: https://issues.apache.org/jira/browse/FLINK-19517
> Project: Flink
> Issue Type: Wish
> Components: Connectors / Kafka, Table SQL / Ecosystem
> Affects Versions: 1.12.0
> Reporter: Kevin Kwon
> Priority: Major
>
> Currently, table creation from SQL client such as below works well
> {code:sql}
> CREATE TABLE kafkaTable (
> user_id BIGINT,
> item_id BIGINT,
> category_id BIGINT,
> behavior STRING,
> ts TIMESTAMP(3)
> ) WITH (
> 'connector' = 'kafka',
> 'topic' = 'user_behavior',
> 'properties.bootstrap.servers' = 'localhost:9092',
> 'properties.group.id' = 'testGroup',
> 'format' = 'avro',
> 'scan.startup.mode' = 'earliest-offset'
> )
> {code}
> Although I would wish for the table creation to support Confluent Kafka
> configuration as well. For example something like
> {code:sql}
> CREATE TABLE kafkaTable (
> user_id BIGINT,
> item_id BIGINT,
> category_id BIGINT,
> behavior STRING,
> ts TIMESTAMP(3)
> ) WITH (
> 'connector' = 'confluent-kafka',
> 'topic' = 'user_behavior',
> 'properties.bootstrap.servers' = 'localhost:9092',
> 'properties.group.id' = 'testGroup',
> 'schema-registry' = 'http://schema-registry.com',
> 'scan.startup.mode' = 'earliest-offset'
> )
> {code}
> If this is enabled, it will be much more convenient to test queries
> on-the-fly that business analysts want to test against with 'Confluent Kafka'
> Additionally, it will be better if we can
> - specify 'parallelism' within WITH clause to support parallel partition
> processing
> - specify custom properties within WITH clause specified in
> [https://docs.confluent.io/5.4.2/installation/configuration/consumer-configs.html]
> - have remote access to SQL client in cluster from local environment
