-- 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.

-- | Creates a value of 'GetDataSourceResponse' with the minimum fields required to make a request.

-- Use one of the following lenses to modify other fields as desired:

-- * 'gdsrsStatus' - The current status of the @DataSource@ . This element can have one of the following values:     * @PENDING@ - Amazon ML submitted a request to create a @DataSource@ .    * @INPROGRESS@ - The creation process is underway.    * @FAILED@ - The request to create a @DataSource@ did not run to completion. It is not usable.    * @COMPLETED@ - The creation process completed successfully.    * @DELETED@ - The @DataSource@ is marked as deleted. It is not usable.
--
-- * 'gdsrsNumberOfFiles' - The number of data files referenced by the @DataSource@ .
--
-- * 'gdsrsLastUpdatedAt' - The time of the most recent edit to the @DataSource@ . The time is expressed in epoch time.
--
-- * 'gdsrsCreatedAt' - The time that the @DataSource@ was created. The time is expressed in epoch time.
--
-- * 'gdsrsComputeTime' - The approximate CPU time in milliseconds that Amazon Machine Learning spent processing the @DataSource@ , normalized and scaled on computation resources. @ComputeTime@ is only available if the @DataSource@ is in the @COMPLETED@ state and the @ComputeStatistics@ is set to true.
--
-- * 'gdsrsDataSourceId' - The ID assigned to the @DataSource@ at creation. This value should be identical to the value of the @DataSourceId@ in the request.
--
-- * 'gdsrsRDSMetadata' - Undocumented member.
--
-- * 'gdsrsDataSizeInBytes' - The total size of observations in the data files.
--
-- * 'gdsrsDataSourceSchema' - The schema used by all of the data files of this @DataSource@ .
--
-- * 'gdsrsStartedAt' - The epoch time when Amazon Machine Learning marked the @DataSource@ as @INPROGRESS@ . @StartedAt@ isn't available if the @DataSource@ is in the @PENDING@ state.
--
-- * 'gdsrsFinishedAt' - The epoch time when Amazon Machine Learning marked the @DataSource@ as @COMPLETED@ or @FAILED@ . @FinishedAt@ is only available when the @DataSource@ is in the @COMPLETED@ or @FAILED@ state.
--
-- * 'gdsrsCreatedByIAMUser' - The AWS user account from which the @DataSource@ was created. The account type can be either an AWS root account or an AWS Identity and Access Management (IAM) user account.
--
-- * 'gdsrsName' - A user-supplied name or description of the @DataSource@ .
--
-- * 'gdsrsLogURI' - A link to the file containing logs of @CreateDataSourceFrom*@ operations.
--
-- * 'gdsrsDataLocationS3' - The location of the data file or directory in Amazon Simple Storage Service (Amazon S3).
--
-- * 'gdsrsComputeStatistics' - The parameter is @true@ if statistics need to be generated from the observation data.
--
-- * 'gdsrsMessage' - The user-supplied description of the most recent details about creating the @DataSource@ .
--
-- * 'gdsrsRedshiftMetadata' - Undocumented member.

-- * 'gdsrsDataRearrangement' - A JSON string that represents the splitting and rearrangement requirement used when this @DataSource@ was created.
