Should use Kafka Schema Registry server

When I used Schema registry server, I found I could not change schema in the same topic anymore. but without schema registry each record has it's own schema inside, so it's easy to change schema anytime.

So how can I change the schema when I'm using schema registry server.

You can change schemas stored in the Confluent Schema Registry, it’s just that the default config enforces backward compatibility. You can change that compatibility config using the following parameter:

avro.compatibility.level

The Avro compatibility type. Valid values are:

  • none (new schema can be any valid Avro schema),

  • backward (new schema can read data produced by latest registered schema),

  • backward_transitive (new schema can read data produced by all previously registered schemas),

  • forward (latest registered schema can read data produced by the new schema),

  • forward_transitive (all previously registered schemas can read data produced by the new schema),

  • full (new schema is backward and forward compatible with latest registered schema),

  • full_transitive (new schema is backward and forward compatible with all previously registered schemas)

Type: string Default: “backward” Importance: high
