Question

我有两个KSQL主题my-topic-1和my-topic-2，并通过AVRO序列化了消息。由于历史原因，my-topic-1模式不是推荐的topic-value格式，而是my-custom-subject-name。

我想通过KSQL将记录从一个主题移到另一个主题。

首先，让我们创建一个流：

CREATE STREAM my-stream-1
    WITH (KAFKA_TOPIC='my-topic-1', VALUE_FORMAT='AVRO');

糟糕：

Avro schema for message values on topic my-topic-1 does not exist in the Schema Registry.
Subject: my-topic-1-value

Possible causes include:
- The topic itself does not exist
        -> Use SHOW TOPICS; to check
- Messages on the topic are not Avro serialized
        -> Use PRINT 'my-topic-1' FROM BEGINNING; to verify
- Messages on the topic have not been serialized using the Confluent Schema Registry Avro serializer
        -> See https://docs.confluent.io/current/schema-registry/docs/serializer-formatter.html
- The schema is registered on a different instance of the Schema Registry
        -> Use the REST API to list available subjects
        https://docs.confluent.io/current/schema-registry/docs/api.html#get--subjects

正在寻找主题my-topic-1-value

有人知道这是否可行吗？ VALUE_AVRO_SCHEMA_FULL_NAME提到了here并没有达到我想要的目的。

这似乎是一个错误。我用一个示例更新了https://github.com/confluentinc/ksql/issues/3188以便重现。我建议我们在那里追踪。

明确指定KSQL流主题名称
