    Basic Examples  (2)

    Create a DataConnectionObject to data located on Amazon S3:

    Wolfram Language code: DataConnectionObject[ <|"ConnectionName" -> "AmazonS3", "Region" -> "us-east-2", "Bucket" -> "wolframdataconnection", "Location" -> "samples/sample.parquet"|>]

    Retrieve data from Amazon S3 using Import:

    Wolfram Language code: Import@DataConnectionObject[ <|"ConnectionName" -> "AmazonS3", "Region" -> "us-east-2", "Bucket" -> "wolframdataconnection", "Location" -> "samples/sample.parquet"|>]

    Authentication  (1)

    Give credentials to Amazon S3:

    Wolfram Language code: Import@DataConnectionObject[ <|"ConnectionName" -> "AmazonS3", "Region" -> "us-east-2", "Bucket" -> "wolframdataconnection", "Location" -> "samples/sample.parquet"|>, Authentication -> <|"AccountKeyID" -> "AccountName", "AccountSecret" -> "Password"|>]
