> ------------------------------------------------------------------------------------------
>
> Key: FLINK-30740
> URL: https://issues.apache.org/jira/browse/FLINK-30740
> Project: Flink
> Issue Type: Bug
> Components: Table Store
> Affects Versions: table-store-0.3.0
> Reporter: Bruno Cadonna
> Priority: Major
>
> If I use Kafka as the log system and set {{auto.create.topics.enabled}} to false in Kafka INSERTs do not work.
> Steps to reproduce:
> # Start a Kafka broker and set {{auto.create.topics.enabled}} to false
> # Issue the following statements
> {code:sql}
> CREATE CATALOG table_store_catalog WITH (
> 'type'='table-store',
> 'warehouse'=<path to object store>
> );
> USE CATALOG table_store_catalog;
> CREATE TABLE word_count (
> word STRING PRIMARY KEY NOT ENFORCED,
> cnt BIGINT
> ) WITH (
> 'log.system' = 'kafka',
> 'kafka.bootstrap.servers' = <address to broker>,
> 'kafka.topic' = 'test-topic,
> 'log.consistency' = 'eventual'
> );
>
> INSERT INTO word_count VALUES ('foo', 1);
> {code}
> The task manager logs show:
> {code}

> Apparently, the Kafka topic is created when the first record is written to the Kafka topic, although I found code to create a Kafka topic explicitly on table creation:
> https://github.com/apache/flink-table-store/blob/f201b507fef88501c4beb4c62807bef818e31be5/flink-table-store-kafka/src/main/java/org/apache/flink/table/store/kafka/KafkaLogStoreFactory.java#L123
> Topic creation should not rely on enabling auto topic creation in Kafka, because users might opt to disable auto topic creation to prevent unexpected costs when a fully-managed Kafka service is used. For example see the Confluent Cloud documentation:
> https://docs.confluent.io/cloud/current/clusters/broker-config.html#enable-automatic-topic-creation
> IMO, when a table is created, the corresponding Kafka topic should be explicitly created.
