Data Delivered to Requester

This flow shows how enabling Requester Pays on a storage bucket shifts the cost of data access to the requester instead of the bucket owner.

Execution Sample

GCP

gsutil requesterpays set on gs://example-bucket

# Requester accesses data
gsutil -u requester-project ls gs://example-bucket

Enable Requester Pays on a bucket, then requester accesses data paying the cost.

Process Table

Step	Action	Requester Pays Enabled?	Who Pays?	Result
1	Enable Requester Pays on bucket	Yes	Requester	Bucket updated to Requester Pays
2	Requester tries to list bucket contents	Yes	Requester	Request accepted, cost billed to requester project
3	Requester tries to access data without specifying project	Yes	Requester	Request denied, must specify billing project
4	Requester accesses data specifying billing project	Yes	Requester	Data delivered, cost billed to requester project
5	Owner accesses bucket	Yes	Owner	Request accepted, cost billed to owner project
6	Requester tries to access bucket without Requester Pays enabled	No	Owner	Request accepted, cost billed to owner project
7	Requester tries to access bucket with Requester Pays enabled but no billing project	Yes	Requester	Request denied, billing project required

💡 Requests without billing project fail when Requester Pays is enabled; otherwise, requester pays cost.

Key Moments - 2 Insights

Why does the request fail if the requester does not specify a billing project when Requester Pays is enabled?

Because with Requester Pays enabled, the requester must specify a billing project to pay for the request. This is shown in execution_table rows 3 and 7 where requests without billing project are denied.

Who pays the cost when Requester Pays is disabled?

The bucket owner pays the cost when Requester Pays is disabled, as shown in execution_table row 6.

Concept Snapshot

Requester Pays configuration shifts storage access costs to the requester.
Enable with: gsutil requesterpays set on gs://bucket
Requester must specify billing project to access data.
Without billing project, requests fail when enabled.
Owner pays costs if disabled.
Useful for public datasets to avoid owner charges.

Full Transcript

Requester Pays configuration in Google Cloud Storage lets the bucket owner require that the person requesting data pays the access costs. First, the owner enables Requester Pays on the bucket. Then, when a requester tries to access data, they must specify a billing project to pay for the request. If they do not specify a billing project, the request is denied. When Requester Pays is disabled, the bucket owner pays for all access costs. This setup is useful for public datasets where the owner wants requesters to cover costs. The key steps are enabling Requester Pays, requester specifying billing project, and cost billing shifting accordingly.

Practice

1. What does enabling Requester Pays on a Google Cloud Storage bucket do?

easy

A. It makes the bucket owner pay for all data access costs.

B. It disables public access to the bucket.

C. It makes the user accessing the data pay for the access costs.

D. It encrypts the data in the bucket automatically.

Solution

1. Step 1: Understand Requester Pays concept

   Requester Pays shifts the cost of data access from the bucket owner to the user who requests the data.

2. Step 2: Identify the cost responsibility

   When enabled, the user accessing the bucket pays for network and operation costs, not the owner.

3. Final Answer:

   It makes the user accessing the data pay for the access costs. -> Option C

4. Quick Check:

   Requester Pays = user pays [OK]

Hint: Requester Pays means user pays for data access costs [OK]

Common Mistakes:

• Thinking bucket owner always pays
• Confusing with access permissions
• Assuming it encrypts data

2. Which command correctly enables Requester Pays on a bucket named my-data-bucket?

easy

A. gsutil set requesterpay gs://my-data-bucket on

B. gsutil requester-pays enable gs://my-data-bucket

C. gsutil enable requester-pays gs://my-data-bucket

D. gsutil requesterpay set on gs://my-data-bucket

Solution

1. Step 1: Recall the correct gsutil syntax

   The correct command to enable Requester Pays is gsutil requesterpay set on followed by the bucket URL.

2. Step 2: Match the command with the bucket name

   gsutil requesterpay set on gs://my-data-bucket uses the exact syntax and bucket name correctly.

3. Final Answer:

   gsutil requesterpay set on gs://my-data-bucket -> Option D

4. Quick Check:

   Correct gsutil syntax = gsutil requesterpay set on gs://my-data-bucket [OK]

Hint: Use 'gsutil requesterpay set on' to enable Requester Pays [OK]

Common Mistakes:

• Using incorrect command verbs like 'enable'
• Misplacing 'requesterpay' keyword
• Wrong order of command arguments

3. Given a bucket with Requester Pays enabled, which gsutil command will successfully copy a file named data.csv from the bucket gs://example-bucket to your local machine?

medium

A. gsutil cp --requester-pays gs://example-bucket/data.csv ./

B. gsutil cp gs://example-bucket/data.csv ./

C. gsutil cp --enable-requester-pays gs://example-bucket/data.csv ./

D. gsutil cp --requesterpay gs://example-bucket/data.csv ./

Solution

1. Step 1: Understand Requester Pays access requirement

   When accessing a Requester Pays bucket, the user must include the --requester-pays flag in the gsutil command.

2. Step 2: Identify the correct flag usage

   gsutil cp --requester-pays gs://example-bucket/data.csv ./ uses the correct flag --requester-pays with the copy command.

3. Final Answer:

   gsutil cp --requester-pays gs://example-bucket/data.csv ./ -> Option A

4. Quick Check:

   Use --requester-pays flag to access Requester Pays buckets [OK]

Hint: Add --requester-pays flag to gsutil commands for Requester Pays buckets [OK]

Common Mistakes:

• Omitting the --requester-pays flag
• Using incorrect flag names
• Assuming normal commands work without flags

4. You try to download a file from a Requester Pays bucket without the --requester-pays flag and get an error. What is the most likely fix?

medium

A. Use a different gsutil version.

B. Add the --requester-pays flag to your gsutil command.

C. Change the bucket permissions to public.

D. Disable Requester Pays on the bucket.

Solution

1. Step 1: Identify cause of error

   Accessing a Requester Pays bucket without the --requester-pays flag causes permission errors because the user is not accepting cost responsibility.

2. Step 2: Apply the correct fix

   Adding the --requester-pays flag tells Google Cloud you accept the charges, fixing the error.

3. Final Answer:

   Add the --requester-pays flag to your gsutil command. -> Option B

4. Quick Check:

   Missing --requester-pays flag causes errors [OK]

Hint: Add --requester-pays flag to fix access errors [OK]

Common Mistakes:

• Trying to disable Requester Pays without permission
• Changing bucket permissions unnecessarily
• Assuming gsutil version causes this error

5. You manage a public dataset bucket with Requester Pays enabled. A user complains they cannot access data using the Google Cloud Console UI. What is the best advice to help them access the data?

hard

A. Tell them to use gsutil with the --requester-pays flag for data access.

B. Advise them to disable Requester Pays on the bucket.

C. Instruct them to request access permissions from the bucket owner.

D. Suggest they use the Cloud Console without any special flags.

Solution

1. Step 1: Understand Requester Pays impact on access methods

   Requester Pays requires users to explicitly accept cost responsibility, usually via command flags like --requester-pays or a confirmation prompt in the UI.

2. Step 2: Identify supported access methods

   While the Cloud Console UI supports Requester Pays with a billing-enabled project and charge acceptance prompt, recommend gsutil with the --requester-pays flag as a reliable alternative when facing UI access issues.

3. Final Answer:

   Tell them to use gsutil with the --requester-pays flag for data access. -> Option A

4. Quick Check:

   Use gsutil + --requester-pays for Requester Pays buckets [OK]

Hint: Use gsutil with --requester-pays for reliable access to Requester Pays buckets [OK]

Common Mistakes:

• Assuming Console UI works without project billing enabled
• Telling users to disable Requester Pays
• Confusing permissions with billing flags
