Hello pretty new to confluent. But I do have a elasticsearch connector set up that works great. I am looking to create my own schema for this json that is being pushed to kafka.

My first question is can my dev set a schema before they push the data to kafka?

If this is not an option is there a good guide to set up a schema or mappings?

Hi Rob,

You may have already figured this out, but yes, you can set a schema before sending data to Kafka. Using the Confluent Schema Registry you can create schemas in JSON Schema, Avro, or Protobuf.

Hi @daveklein , I have a similar question around this. I am trying to send some json records to confluent kafka topic and I want my schema to get registered. I am using kafka-json-schema-serializer but the json record field names are not getting registered properly.

More about what I am trying to do [Click here](https://stackoverflow.com/questions/68621280/jsonschema-values-not-sent-when-using-scala-case-class)

Any suggestions?  
Thanks.
