Cloud Storage - Class A and B Operations

[dougsaraiva]

Example: In a Bucket containing 1,000 objects, when performing a Class A operation, such as storage.objects.list or storage.objects.copy, to list or copy all objects, will this action be counted as a single operation? Or will each object be considered a separate operation, resulting in a total of a thousand operations?

Additionally, regarding the storage.*.insert and storage.*.get operations, each inserted or retrieved object is counted as an individual operation, correct?

Hi @dougsaraiva,

Welcome to Google Cloud Community!

Class A operations:

• Counted as a single operation, even if they act on multiple objects.
• Examples:
  • Listing all objects in a bucket.
  • Copying all objects in a bucket.
  • Deleting multiple objects in a single request.

Class B operations:

• Counted individually for each object they act on.
• Examples:
  • Inserting each object.
  • Retrieving each object.
  • Composing multiple objects into a single object (one operation for composition, one per component object).

Key Points:

• Class A operations are generally more expensive than Class B operations.
• Batch operations to optimize costs.
• Pricing varies slightly for Regional Buckets.
• Certain operations are free.

Additional Insights:

• Consider cost implications for large-scale operations.
• Refer to official documentation for latest pricing information.
