Example 6 with SerdeFeatures

use of io.confluent.ksql.serde.SerdeFeatures in project ksql by confluentinc.

the class DefaultSchemaInjector method getCreateAsKeySchema.

    // to have key schema inference always result in an unwrapped key

Example 7 with SerdeFeatures

use of io.confluent.ksql.serde.SerdeFeatures in project ksql by confluentinc.

the class SchemaRegisterInjector method registerForCreateSource.

    // we can assume that the kafka topic is always present in the
