Please subscribe to the product from AWS Marketplace and Activate the Glue connector from AWS Glue Studio .

The Iceberg connector enables you to access iceberg tables from your Glue jobs. In particular, you can operate DDLs, read/write data, time-travels and streaming writes for the Iceberg sources. Further details about the Apache Iceberg, please see https://iceberg.apache.org/ .

Using the Apache Iceberg Connector

Here's the steps to set up the Iceberg connector. For more details about using Iceberg on AWS, please refer to https://iceberg.apache.org/aws/ .

Required Spark configuration

Before using this connector, you need to set the following Spark configuration for communication between this connector and the Glue Data Catalog.

You can set the configuration on the job parameter in your Glue job or on the scripts in your Glue job. Please note that the configuration related to spark.sql.extensions is optional, however that's recommended for accessing full operations of Iceberg.

Set on the job parameter

• Key: --conf
• Value: spark.sql.catalog.<catalog_name>=org.apache.iceberg.spark.SparkCatalog --conf spark.sql.catalog.<catalog_name>.warehouse=<S3_PATH> --conf spark.sql.catalog.<catalog_name>.catalog-impl=org.apache.iceberg.aws.glue.GlueCatalog --conf spark.sql.catalog.<catalog_name>.io-impl=org.apache.iceberg.aws.s3.S3FileIO --conf spark.sql.extensions=org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions

Set on the Glue job script:

from pyspark.sql import SparkSession from pyspark.context import SparkContext

spark = SparkSession.builder \ .config(f"spark.sql.catalog.<catalog>", "org.apache.iceberg.spark.SparkCatalog") \ .config(f"spark.sql.catalog.<catalog>.warehouse", "s3://bucket/path/") \ .config(f"spark.sql.catalog.<catalog>.catalog-impl", "org.apache.iceberg.aws.glue.GlueCatalog") \ .config(f"spark.sql.catalog.<catalog>.io-impl", "org.apache.iceberg.aws.s3.S3FileIO") \ .config(f"spark.sql.extensions","org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions") \ .getOrCreate()

Connector options

You can pass the following options to the connector.

• path - An Iceberg table name such as <catalog_name>.<database>.<table>.
• as-timestamp-of or snapshotid (optional, set only for read) - You can operate "Time travel" queries by setting this parameter. Please see the document  about the time-travel.

NOTE: Glue natively supports Iceberg. Please refer to https://docs.aws.amazon.com/glue/latest/dg/aws-glue-programming-etl-format-iceberg.html .
