   In general, each compute engine has its own page to explain loading custom catalog, that's why only spark example is given in AWS page. Probably good to add this note in the AWS page. I am gathering the small fixes for the 0.11 website right now, I will update them all at once, thanks for the suggestion.
   
   To answer your question around Flink, use the guide here: https://iceberg.apache.org/flink/#custom-catalog, the minimum you need is:
   
   ```
   CREATE CATALOG my_catalog WITH (
     'type'='iceberg',
     'catalog-impl'='org.apache.iceberg.aws.glue.GlueCatalog',
     'warehouse'='s3://my-bucket/my/key/prefix'
   );
   ```
   
   AWS credentials are accessed through the default credential chain that tries to retrieve credentials in a series of approaches: https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/credentials.html
   
   If you need more customization such as endpoint, you can load your own AwsClientFactory through the guide https://iceberg.apache.org/aws/#aws-client-customization
