Feature #17349
Updated by Peter Amstutz over 3 years ago
This specification is for the server side (client side of this will be on separate tickets,). Make sure that endpoint /arvados/v1/collections has all desired functionality, tests and documentation for controller and railsapi This ticket will cover (api) * railsapi (including storing in the database) * controller * documentation updates the current behaviour * test This ticket will not cover * client behaviour * keep-balance behavirour Acording to the documentation the current behaviour for collections' "replicas_desired" is to accept a Number[1] or 'null'. Also there is an undocumented attribute "storage_classes_desired" and "storage_classes_confirmed". "MyStorageClass" is an example name that has to match with the StorageClass configuration setting on the volume but has no particular meaning for Arvados. Valid values: |_. replicas_desired |_. storage_classes_desired |_. defaultCollectionReplication |_. Collection Effective Value |_. Notes | | null (or omited from the request) | null | 3 | {"default": 3} | | | null (or omited from the request) | null | 2 | {"default": 2} | current behaviour see [2] | | 42 | null | 2 | {"default": 42} | | | 34 | null | 2 | {"default": 34} | | | 1 |["MyStorageClass"] | 2 | {"default": 0, "MyStorageClass": 1} | | | 1 |["default","MyStorageClass"] | 2 | {"default": 1, "MyStorageClass": 1} | | is this correct?| | null |["default","MyStorageClass"] | 2 | {"default": 2, "MyStorageClass": 2} | | How does defaultCollectionReplication affects this?| The "Effective value" is the amount of copies stored in each storage class, this column will help to clarify cases in following tickets To be talked in next grooming session: * For the error send the user an error, we only will discuss the API errors. arv-put, arvados-cwl-runner and other clients will have their own ticket * How will backward compatibility works here?
