Data Ingestion and Transformation

A data engineer must create an enterprise data catalog from the company’s Amazon S3 buckets and Amazon RDS databases. The data catalog must contain storage-format metadata for the cataloged data.

Which solution meets these requirements with the LEAST effort?

  • A Use an AWS Glue crawler to scan the S3 buckets and RDS databases and build a data catalog. Use data stewards to inspect the data and update the data catalog with the data format.
  • B Use an AWS Glue crawler to build a data catalog. Use AWS Glue crawler classifiers to recognize the format of data and store the format in the catalog.
  • C Use Amazon Macie to build a data catalog and to identify sensitive data elements. Collect the data format information from Macie.
  • D Use scripts to scan data elements and to assign data classifications based on the format of the data.
Explanation

AWS Glue crawlers can populate the AWS Glue Data Catalog from Amazon S3 and Amazon RDS data sources. Crawlers use classifiers to recognize a data format and infer its schema; the resulting classification and schema are stored in the Data Catalog, providing the required format metadata without manual inspection or custom scripts.
