Review comment: The `AssumeRoleCredentialsFactory` is an example for it, I can give another example with more complicated customer use case: ```java package com.my.team; import software.amazon.awssdk.auth.credentials.ContainerCredentialsProvider; import software.amazon.awssdk.awscore.client.builder.AwsClientBuilder; import software.amazon.awssdk.services.glue.GlueClient; import software.amazon.awssdk.services.glue.GlueClientBuilder; import software.amazon.awssdk.services.s3.S3ClientBuilder; import software.amazon.awssdk.services.sts.auth.StsAssumeRoleCredentialsProvider; import software.amazon.awssdk.services.sts.auth.StsAssumeRoleWithSamlCredentialsProvider; public class CustomCredentialsFactory implements AwsClientCredentialsFactory { @Override public void configure(AwsClientBuilder clientBuilder) { if (clientBuilder instanceof S3ClientBuilder) { clientBuilder.credentialsProvider(StsAssumeRoleWithSamlCredentialsProvider.builder() .refreshRequest(...) .build()); } else if (clientBuilder instanceof GlueClientBuilder) { clientBuilder.credentialsProvider(StsAssumeRoleCredentialsProvider.builder() .refreshRequest(...) .build()) } else { clientBuilder.credentialsProvider(ContainerCredentialsProvider.builder().build()); } } } ``` And it can be started with: ``` spark-sql --jars iceberg-spark3-runtime.jar \ --conf spark.sql.catalog.my_catalog=org.apache.iceberg.spark.SparkCatalog \ --conf spark.sql.catalog.my_catalog.catalog-impl=org.apache.iceberg.aws.glue.GlueCatalog \ --conf spark.sql.catalog.my_catalog.warehouse=s3://my-bucket \ --conf spark.sql.catalog.my_catalog.client.credentials-factory=com.my.team.CustomCredentialsFactory ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
