whisper-bye edited a comment on issue #2992: schemas feature request URL: https://github.com/apache/pulsar/issues/2992#issuecomment-601623655 @nha @merlimat sorry for asking. In my case, I have some raw json string data send to topic and can't hard code pojo class, I want to use the pulsar schema feature to validation the structure. I have a topic "my-topic" and associated with json schema in below, then I try to transmission some message. ``` var producer = client.newProducer(Schema.AUTO_PRODUCE_BYTES(); producer.send("{\"y\": 1}".getBytes()); // here! the value is 1(number) not string. var reader = client.newReader(Schema.AUTO_CONSUME()) var message = reader.readNext(); I got {"y": 1} ``` my question is how pulsar schema works? The message should be rejected. ``` { "version": 1, "schemaInfo": { "name": "my-topic", "schema": { "type": "record", "name": "Data", "namespace": "com.iot.test", "fields": [ { "name": "y", "type": [ "null", "string" ] } ] }, "type": "JSON", "properties": { "__alwaysAllowNull": "true" } } } ```
