Creates (registers) a data catalog with the specified name and properties

Source: R/athena_operations.R
athena_create_data_catalog.Rd

Creates (registers) a data catalog with the specified name and properties. Catalogs created are visible to all users of the same Amazon Web Services account.

See https://www.paws-r-sdk.com/docs/athena_create_data_catalog/ for full documentation.

Usage

athena_create_data_catalog(
  Name,
  Type,
  Description = NULL,
  Parameters = NULL,
  Tags = NULL
)

Arguments

Name

[required] The name of the data catalog to create. The catalog name must be unique for the Amazon Web Services account and can use a maximum of 127 alphanumeric, underscore, at sign, or hyphen characters. The remainder of the length constraint of 256 is reserved for use by Athena.

For FEDERATED type the catalog name has following considerations and limits:

  • The catalog name allows special characters such as _ , @ , \ , - . These characters are replaced with a hyphen (-) when creating the CFN Stack Name and with an underscore (_) when creating the Lambda Function and Glue Connection Name.

  • The catalog name has a theoretical limit of 128 characters. However, since we use it to create other resources that allow less characters and we prepend a prefix to it, the actual catalog name limit for FEDERATED catalog is 64 - 23 = 41 characters.

Type

[required] The type of data catalog to create: LAMBDA for a federated catalog, GLUE for an Glue Data Catalog, and HIVE for an external Apache Hive metastore. FEDERATED is a federated catalog for which Athena creates the connection and the Lambda function for you based on the parameters that you pass.

For FEDERATED type, we do not support IAM identity center.

Description

A description of the data catalog to be created.

Parameters

Specifies the Lambda function or functions to use for creating the data catalog. This is a mapping whose values depend on the catalog type.

  • For the HIVE data catalog type, use the following syntax. The metadata-function parameter is required. The sdk-version parameter is optional and defaults to the currently supported version.

    metadata-function=lambda_arn, sdk-version=version_number

  • For the LAMBDA data catalog type, use one of the following sets of required parameters, but not both.

    • If you have one Lambda function that processes metadata and another for reading the actual data, use the following syntax. Both parameters are required.

      metadata-function=lambda_arn, record-function=lambda_arn

    • If you have a composite Lambda function that processes both metadata and data, use the following syntax to specify your Lambda function.

      function=lambda_arn

  • The GLUE type takes a catalog ID parameter and is required. The catalog_id is the account ID of the Amazon Web Services account to which the Glue Data Catalog belongs.

    catalog-id=catalog_id

    • The GLUE data catalog type also applies to the default AwsDataCatalog that already exists in your account, of which you can have only one and cannot modify.

  • The FEDERATED data catalog type uses one of the following parameters, but not both. Use connection-arn for an existing Glue connection. Use connection-type and connection-properties to specify the configuration setting for a new connection.

    • connection-arn:<glue_connection_arn_to_reuse>

    • lambda-role-arn (optional): The execution role to use for the Lambda function. If not provided, one is created.

    • connection-type:MYSQL|REDSHIFT|...., connection-properties:"<json_string>"

      For \<json_string\> , use escaped JSON text, as in the following example.

      "{\"spill_bucket\":\"my_spill\",\"spill_prefix\":\"athena-spill\",\"host\":\"abc12345.snowflakecomputing.com\",\"port\":\"1234\",\"warehouse\":\"DEV_WH\",\"database\":\"TEST\",\"schema\":\"PUBLIC\",\"SecretArn\":\"arn:aws:secretsmanager:ap-south-1:111122223333:secret:snowflake-XHb67j\"}"

Tags

A list of comma separated tags to add to the data catalog that is created. All the resources that are created by the create_data_catalog API operation with FEDERATED type will have the tag federated_athena_datacatalog="true". This includes the CFN Stack, Glue Connection, Athena DataCatalog, and all the resources created as part of the CFN Stack (Lambda Function, IAM policies/roles).
