# Configure ksqlDB for Avro, Protobuf, and JSON in ksqlDB for Confluent Platform ksqlDB integrates with [Confluent Schema Registry](../../../schema-registry/index.md#schemaregistry-intro) for supported [serialization formats](../../reference/serialization.md#ksqldb-serialization-formats), automatically retrieving and registering schemas so you don’t need to define columns and data types manually in `CREATE` statements. For more information, see [Schema Inference](../schema-registry-integration.md#ksqldb-schema-inference). You must configure the REST endpoint of Schema Registry by setting `ksql.schema.registry.url` in the ksqlDB Server configuration file (`/etc/ksqldb/ksql-server.properties`). For more information, see [Configure ksqlDB for Secured Confluent Schema Registry](security.md#ksqldb-installation-security-configure-for-secured-sr). Schema Registry is [included by default](../../../get-started/platform-quickstart.md#quickstart) with Confluent Platform. #### IMPORTANT Don’t use the SET statement in the ksqlDB CLI to configure the registry endpoint.
