Which feature of S3 allows for retrieving archived data quickly?

The feature that allows for retrieving archived data quickly in Amazon S3 is Glacier Select. Glacier Select enables users to perform SQL queries on data stored in the Amazon S3 Glacier storage class without the need to retrieve the entire object. This capability significantly speeds up access to specific data within large archives, allowing users to quickly obtain only the relevant information they need, rather than incurring the time and cost of retrieving the whole archive.

Using Glacier Select is particularly advantageous for applications that require quick data retrieval from archives, making it possible to analyze and extract necessary data directly from the archived files. This feature is ideal for organizations that manage large datasets and need efficient access to archived information for analytics or compliance purposes.

Other storage classes, like Infrequent Access, Standard Storage, and Intelligent-Tiering, do not provide the same level of direct access to specific data within archived files, making Glacier Select the most suitable option for fast retrieval from archived data.
