Learn to create a connection to Confluent Schema Registry that is used in conjunction with the Confluent Kafka connection to serve as a source or target for a OCI GoldenGate Big Data deployment.

Before you create the connection, ensure that you review how OCI GoldenGate connects to your source and targets.

1. From the OCI GoldenGate Overview page, click Connections.
   You can also click Create Connection under the Get started section and skip to step 3.
2. On the Connections page, click Create Connection.
3. On the Create Connection page, complete the fields as follows:
   1. For Name, enter a name for the connection.
   2. (Optional) For Description, enter a description that helps you distinguish this connection from others.
   3. For Compartment, select the compartment in which to create the connection.
   4. From the Type dropdown, select Confluent Schema Registry.
   5. For Bootstrap servers, select a Traffic routing method:
      • Shared endpoint, to share an endpoint with the assigned deployment. You must allow connectivity from the deployment's ingress IP.
      • Dedicated endpoint, for network traffic through a dedicated endpoint in the assigned subnet in your VCN. You must allow connectivity from this connection's ingress IPs.

        Note:

        • If a dedicated connection remains unassigned for seven days, then the service converts it to a shared connection.
        • Learn more about Oracle GoldenGate connectivity.
   6. Enter the Confluent Schema Registry Host and Port number.

      Note:

      If a private IP is entered, then OCI GoldenGate rewrites the private IP in the format, ip-10-0-0-0.ociggsvc.oracle.vcn.com.
   7. Select an Security protocol from the dropdown:
      • Plaintext
      • SASL over plaintext
      • SASL over SSL
      • SSL

      Depending on your Security protocol selection, complete the following fields:

      1. For Username, enter the Confluent Schema Registry connection string, and then enter the Password.

         Note:

         To use password secrets, ensure that you select Use secrets in vault in the Settings tab under Advanced Options, located at the bottom of this form.
      2. (Optional) Drag-and-drop or select a Truststore file, and then enter the Truststore password.
      3. (Optional) Drag-and-drop or select a Keystore file, and then enter the Keystore password and SSL key passsword.
   8. Expand Show advanced options. You can configure the following options:
      • Security
        • Select Use Oracle-managed encryption key to leave all encryption key management to Oracle.
        • Select Use customer-managed encryption key to select a specific encryption key stored in your OCI Vault to encrypt your connection credentials.
      • Settings
        • Select Use vault secrets to use a password secret for your connection.
        • If using this connection for Extract, then drag and drop or select the Consumer or Producer properties file under Additional properties.
        • To use Snappy compression in Kafka replication, drag and drop or select Producer properties, and change replication settings as discussed in Using Compression OCI GoldenGate (Confluent) Kafka Replication.
        • To capture from Kafka, create a Kafka Consumer properties file with one of the following deserializers or converters:
          • Kafka Consumer properties for JSON deserializer:

            key.deserializer=org.apache.kafka.common.serialization.ByteArrayDeserializer
            value.deserializer=org.apache.kafka.common.serialization.ByteArrayDeserializer

          • Kafka Consumer properties for JSON converter:

            key.converter=org.apache.kafka.connect.json.JsonConverter
            value.converter=org.apache.kafka.connect.json.JsonConverter

          • Kafka Consumer properties for Avro converter:

            key.converter=io.confluent.connect.avro.AvroConverter
            value.converter=io.confluent.connect.avro.AvroConverter
