Options

--catalog-id (string)

The ID of the Data Catalog where the table resides. If none is provided, the Amazon Web Services account ID is used by default.

--database-name (string)

The name of the database in the catalog in which the table resides. For Hive compatibility, this name is entirely lowercase.

--name (string)

The name of the table for which to retrieve the definition. For Hive compatibility, this name is entirely lowercase.

--transaction-id (string)

The transaction ID at which to read the table contents.

--query-as-of-time (timestamp)

The time as of when to read the table contents. If not set, the most recent transaction commit time will be used. Cannot be specified along with TransactionId .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

--output (string)

The formatting style for command output.

• json
• text
• table

--query (string)

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.
