Compass Persistent Storage Projects
Compass Persistent Storage Projects Overview
Compass Persistent Storage (CPS) is a Google Cloud Platform (GCP) project for current Compass Users who are working on a project in Eureka. While Eureka instances may be decommissioned at the time of a significant update, CPS projects live on. CPS projects have different GCP resources enabled for Users to access, including:
Google Cloud Storage and Google BigQuery for storage. Users may opt to store data not delivered by Health Data Compass under these resources
Google Cloud Source Repository and Google Artifact Registry. Users may look to these to support project code sharing and versioning
Obtaining a Compass Persistent Storage project
Please visit the ‘Getting Started’ section for instruction on how to request a CPS project to support your work in Eureka.
How does billing work for a Compass Persistent Storage project?
Like Eureka instances, Eureka Instance Owners are billed quarterly for CPS project. Costs depend on storage use, users accessing the project, and a Compass Support Service fee. See here for the current fee.
Using a Compass Persistent Storage project
To protect against unintended deletions of data, users may place ‘object holds’ on objects stored in a bucket. This essentially allows a user to ‘mark’ an object as being protected against all deletes and overwrites. This requires a user to identify objects you want to protect in advance. Also, please note that if you attempt to delete objects in bulk under a bucket it will fail if any have a hold on them. See here for guidance.
