Are you using a specific S3 blob storage cloud provider? Do you store information in the pipeline?
💡 Model Answer
Amazon S3 is an object storage service that can be used as a blob store for data pipelines. It offers high durability, scalability, and low latency. In a pipeline, you typically write raw data to an S3 bucket, then process it with services like AWS Glue, EMR, or Databricks. Storing information in the pipeline means persisting intermediate results or metadata in S3 so that downstream jobs can access them. You can use S3 prefixes to organize data by date, source, or processing stage. Security is handled via IAM policies, bucket policies, and encryption (SSE‑S3 or SSE‑KMS). Using S3 as a central data lake allows you to decouple storage from compute, enabling cost‑effective, elastic processing.
