Connectors and dependencies

Connectors enable you to read and write data across various technologies. Managed Service for Apache Flink bundles three default connectors with your Studio notebook. You can also use custom connectors. For more information about connectors, see Table & SQL Connectors in the Apache Flink documentation.

Default connectors

If you use the AWS Management Console to create your Studio notebook, Managed Service for Apache Flink includes the following custom connectors by default: flink-sql-connector-flink, flink-connector-kafka_2.12 and aws-msk-iam-auth. To create a Studio notebook through the console without these custom connectors, choose the Create with custom settings option. Then, when you get to the Configurations page, clear the checkboxes next to the two connectors.

If you use the CreateApplication API to create your Studio notebook, the flink-sql-connector-flink and flink-connector-kafka connectors aren't included by default. To add them, specify them as a MavenRefernce in the CustomArtifactsConfiguration data type as shown in the following examples.

The aws-msk-iam-auth connector is the connector to use with Amazon MSK that includes the feature to automatically authenticate with IAM.

Note

The connector versions shown in the following example are the only versions that we support.

For the Kinesis connector:

"CustomArtifactsConfiguration": [{
"ArtifactType": "DEPENDENCY_JAR",            
   "MavenReference": {
"GroupId": "org.apache.flink",

      "ArtifactId": "flink-sql-connector-kinesis",
      "Version": "1.15.4"

   }      
}]

For authenticating with AWS MSK through AWS IAM:

"CustomArtifactsConfiguration": [{
"ArtifactType": "DEPENDENCY_JAR",            
   "MavenReference": {
"GroupId": "software.amazon.msk",
      "ArtifactId": "aws-msk-iam-auth",
      "Version": "1.1.6"
   }      
}]
            
For the Apache Kafka connector:  

"CustomArtifactsConfiguration": [{
"ArtifactType": "DEPENDENCY_JAR",            
   "MavenReference": {
"GroupId": "org.apache.flink",

      "ArtifactId": "flink-connector-kafka",
      "Version": "1.15.4"

   }      
}]

To add these connectors to an existing notebook, use the UpdateApplication API operation and specify them as a MavenReference in the CustomArtifactsConfigurationUpdate data type.

Note

You can set failOnError to true for the flink-sql-connector-kinesis connector in the table API.

Dependencies and custom connectors

To use the AWS Management Console to add a dependency or a custom connector to your Studio notebook, follow these steps:

1. Upload your custom connector's file to Amazon S3.

2. In the AWS Management Console, choose the Custom create option for creating your Studio notebook.

3. Follow the Studio notebook creation workflow until you get to the Configurations step.

4. In the Custom connectors section, choose Add custom connector.

5. Specify the Amazon S3 location of the dependency or the custom connector.

6. Choose Save changes.

To add a dependency JAR or a custom connector when you create a new Studio notebook using the CreateApplication API, specify the Amazon S3 location of the dependency JAR or the custom connector in the CustomArtifactsConfiguration data type. To add a dependency or a custom connector to an existing Studio notebook, invoke the UpdateApplication API operation and specify the Amazon S3 location of the dependency JAR or the custom connector in the CustomArtifactsConfigurationUpdate data type.

Note

When you include a dependency or a custom connector, you must also include all its transitive dependencies that aren't bundled within it.
