Add a “delete” method to the v2 storage interface¶
https://storyboard.openstack.org/#!/story/2005395
Problem Description¶
Note
This spec is the detailed implementation of one part of a larger spec. If you haven’t read it yet, please see https://specs.openstack.org/openstack/cloudkitty-specs/specs/train/reset_scope_state.html
Currently, there is no way to delete data from a v2 storage backend via cloudkitty. However, this is required in order to reset the state of a scope (see note above).
Proposed Change¶
A delete method will be added to the v2 storage interface and implemented
in the v2 storage drivers. It will take three parameters:
begin(datetime object, optional): The start of the period for which data should be deleted.end(datetime object, optional): The end of the period for which data should be deleted.filters(dict, optional): A dict of optional filters allowing to select data marked for deletion.
Alternatives¶
None.
Data model impact¶
No changes will be made to the data model. However, it will be possible to delete data from the storage backend through cloudkitty now.
REST API impact¶
None. Described in another spec.
Security impact¶
None. API security impact is described in other specs.
Notifications Impact¶
None. Described in another spec.
Other end user impact¶
None.
Performance Impact¶
Data deletion may slow down and put some load on the storage backend.
Other deployer impact¶
None.
Developer impact¶
Changes related to scope state reset will need to be rebased on this change.

Work Items¶
Add the delete method to the v2 storage interface and implement it in the
InfluxDB storage driver.
Dependencies¶
Spec: allowing to get/reset the state of a scope. https://specs.openstack.org/openstack/cloudkitty-specs/specs/train/reset_scope_state.html
Testing¶
In addition to unit tests, Tempest scenarios testing the whole scope state reset action will be added.
Documentation Impact¶
The delete method will be added to the autogenerated documentation.
