get-data-source

Description

Returns a DataSource that includes metadata and data file information, as well as the current status of the DataSource .

GetDataSource provides results in normal or verbose format. The verbose format adds the schema description and the list of files pointed to by the DataSource to the normal format.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  get-data-source
--data-source-id <value>
[--verbose | --no-verbose]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--data-source-id (string)

The ID assigned to the DataSource at creation.

--verbose | --no-verbose (boolean)

Specifies whether the GetDataSource operation should return DataSourceSchema .

If true, DataSourceSchema is returned.

If false, DataSourceSchema is not returned.

--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.

See 'aws help' for descriptions of global parameters.
