## Properties

- `catalogId`: string (required) — The ID of the data catalog to create the catalog object in.

  Currently, this should be the AWS account ID.

  > To specify the account ID, you can use the `Ref` intrinsic function with the `AWS::AccountId` pseudo parameter. For example: `!Ref AWS::AccountId` .

- `connectionInput`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnConnection.ConnectionInputProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_glue.CfnConnection.ConnectionInputProperty.html) (required) — The connection that you want to create.

- `tags`: any — The collection of tags.

  Each tag element is associated with a given resource.
