Google Cloud Storage: Buckets, Classes and Best Practices
Google Cloud Storage holds the raw files of almost every data platform on Google Cloud. This guide covers buckets and naming, choosing a location, the storage classes with their minimum durations and retrieval fees, lifecycle rules and how conflicts between them are resolved, soft delete, and access control.
Cloud Storage to BigQuery: Building an Ingestion Layer
