Requirement Clarification / Update¶

• Images must be identified using the GUID from the dummy table named Patients .

• Images should be retrieved from the S3 bucket, not from the physical folder .

• A Windows Service is responsible for:

  • Monitoring the physical folder
  • Uploading/syncing images to the S3 bucket

• The application/service should:

  • Pull images only from the S3 bucket
  • Use the Patients.GUID to map and fetch the corresponding images

Note:
Direct access to the local/physical image folder is not required from the application side once images are available in S3.

Requirement Clarification / Update¶¶

• Update the existing API to accept PatientId (GUID) as the input parameter.
• The API should retrieve patient images from the S3 bucket using the provided PatientId (GUID), which maps to Patients.GUID in the dummy Patients table.
• Images must be fetched only from the S3 bucket and not from the physical/local folder.

S3 & Testing Setup¶

• A new S3 bucket will be created specifically for this implementation.
• Dummy images will be uploaded to the new bucket and used for testing and validation .

Note

The application/API should not access the physical folder directly .
