# Connecting to the Data Catalog using Amazon Glue Iceberg REST extension endpoint
<a name="connect-glue-iceberg-rest-ext"></a>

 Amazon Glue Iceberg REST extension endpoint provides additional APIs, which are not present in the Apache Iceberg REST specification, and provides server-side scan planning capabilities. These additional APIs are used when you access tables stored in Amazon Redshift managed storage. The endpoint is accessible from an application using Apache Iceberg Amazon Glue Data Catalog extensions. 

**Endpoint configuration** – A catalog with tables in the Redshift managed storage is accessible using the service endpoint. Refer to the [Amazon Glue service endpoints reference guide](https://docs.aws.amazon.com/general/latest/gr/glue.html#glue_region) for the region-specific endpoint. For example, when connecting to Amazon Glue in the us-east-1 Region, you need to configure the endpoint URI property as follows:

```
Endpoint : https://glue.{{us-east-1}}.amazonaws.com/extensions
```

```
catalog_name = {{"myredshiftcatalog"}}
aws_account_id = {{"123456789012"}}
aws_region = "us-east-1"
spark = SparkSession.builder \
    .config("spark.sql.defaultCatalog", catalog_name) \
    .config(f"spark.sql.catalog.{catalog_name}", "org.apache.iceberg.spark.SparkCatalog") \
    .config(f"spark.sql.catalog.{catalog_name}.type", "glue") \
    .config(f"spark.sql.catalog.{catalog_name}.glue.id", "{123456789012}:redshiftnamespacecatalog/redshiftdb") \
    .config("spark.sql.extensions","org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions") \
    .getOrCreate()
```
