【问题描述】:
我有两个 KSQL 主题 my-topic-1 和 my-topic-2,消息通过 AVRO 序列化。由于历史原因,my-topic-1 架构不是推荐的topic-value 格式,而是my-custom-subject-name。
我想通过 KSQL 将记录从一个主题移动到另一个主题。
首先,让我们创建一个流:
CREATE STREAM my-stream-1
WITH (KAFKA_TOPIC='my-topic-1', VALUE_FORMAT='AVRO');
哎呀:
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
有人知道这是否可能吗? VALUE_AVRO_SCHEMA_FULL_NAME 提到 here 没有做我想做的事。
