CREATE CATALOG INTEGRATION (AWS Glue)¶

Syntax¶

CREATE [ OR REPLACE ] CATALOG INTEGRATION [IF NOT EXISTS]
  <name>
  CATALOG_SOURCE = GLUE
  TABLE_FORMAT = ICEBERG
  GLUE_AWS_ROLE_ARN = '<arn-for-AWS-role-to-assume>'
  GLUE_CATALOG_ID = '<glue-catalog-id>'
  [ GLUE_REGION = '<AWS-region-of-the-glue-catalog>' ]
  CATALOG_NAMESPACE = '<catalog-namespace>'
  ENABLED = { TRUE | FALSE }
  [ COMMENT = '<string_literal>' ]

Required parameters¶

name

String that specifies the identifier (name) for the catalog integration; must be unique in your account.

In addition, the identifier must start with an alphabetic character and cannot contain spaces or special characters unless the entire identifier string is enclosed in double quotes (for example, "My object"). Identifiers enclosed in double quotes are also case sensitive.

For more information, see Identifier requirements.

CATALOG_SOURCE = GLUE

Specifies that the integration is for AWS Glue.

TABLE_FORMAT = ICEBERG

Specifies Glue Iceberg tables.

GLUE_AWS_ROLE_ARN = 'arn-for-AWS-role-to-assume'

Specifies the Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) role to assume.

GLUE_CATALOG_ID = 'glue-catalog-id'

Specifies the ID of your AWS account.

CATALOG_NAMESPACE = 'catalog-namespace'

Specifies your AWS Glue Data Catalog namespace (for example, my_glue_database). This is the default namespace for all Iceberg tables that you associate with this catalog integration. You can override this value by specifying the namespace at the table level when you create a table.

ENABLED = { TRUE | FALSE }

Specifies whether the catalog integration is available to use for Iceberg tables.

• TRUE lets users create new Iceberg tables that reference this integration. Existing Iceberg tables that reference this integration function normally.

• FALSE prevents users from creating new Iceberg tables that reference this integration. Existing Iceberg tables that reference this integration cannot access the catalog in the table definition.

Optional parameters¶

[ GLUE_REGION = 'AWS-region-of-the-glue-catalog' ]

Specifies the AWS Region of your AWS Glue Data Catalog. You must specify a value for this parameter if your Snowflake account is not hosted on AWS. Otherwise, the default region is the Snowflake deployment region for the account.

COMMENT = 'string_literal'

String (literal) that specifies a comment for the integration.

Default: No value

Access control requirements¶

A role used to execute this SQL command must have the following privileges at a minimum:

For instructions on creating a custom role with a specified set of privileges, see Creating custom roles.

For general information about roles and privilege grants for performing SQL actions on securable objects, see Overview of Access Control.

Usage notes¶

• You cannot modify an existing catalog integration; use a CREATE OR REPLACE CATALOG INTEGRATION statement instead.

• You can’t drop or replace a catalog integration if one or more Iceberg tables are associated with the catalog integration.

  To view the tables that depend on a catalog integration, you can use the SHOW ICEBERG TABLES command and a query using RESULT_SCAN that filters on the catalog_name column.

  Note

  The column identifier (catalog_name) is case-sensitive. Specify the column identifier exactly as it appears in the SHOW ICEBERG TABLES output.

  For example:

  SHOW ICEBERG TABLES;
  
  SELECT * FROM TABLE(
    RESULT_SCAN(
        LAST_QUERY_ID()
      )
    )
    WHERE "catalog_name" = 'my_catalog_integration_1';
  

  Copy

• Regarding metadata:

  Attention

  Customers should ensure that no personal data (other than for a User object), sensitive data, export-controlled data, or other regulated data is entered as metadata when using the Snowflake service. For more information, see Metadata fields in Snowflake.

• CREATE OR REPLACE <object> statements are atomic. That is, when an object is replaced, the old object is deleted and the new object is created in a single transaction.

Examples¶

The following example creates a catalog integration that uses an AWS Glue catalog source. When you create a catalog integration for Glue, you must complete additional steps to establish a trust relationship between Snowflake and the Glue Data Catalog. For information, see Configure a catalog integration for AWS Glue.

CREATE CATALOG INTEGRATION glueCatalogInt
  CATALOG_SOURCE = GLUE
  CATALOG_NAMESPACE = 'myNamespace'
  TABLE_FORMAT = ICEBERG
  GLUE_AWS_ROLE_ARN = 'arn:aws:iam::123456789012:role/myGlueRole'
  GLUE_CATALOG_ID = '123456789012'
  GLUE_REGION = 'us-east-2'
  ENABLED = TRUE;
