Remove Job Binary Internal¶
https://blueprints.launchpad.net/sahara/+spec/remove-job-binary-internal
Job binary internal is not needed now, since swift and manila are available (and possibly other storage options in the future) and these are more suitable options for storage.
Problem description¶
Job binary internal is a job binary storage option that is kept in Sahara’s internal database, this option should not be available anymore since there are better storage options (swift, manila, …).
Besides that, Sahara’s internal database should be used only to Sahara’s data storage. Allowing job binaries to be stored in Sahara’s database isn’t only unneeded, but also a possible source of problems, since it increases the size of the database. It also opens a loophole for free storage. It’s definitely the wrong tool for the job.
Also, it’s important to notice that this change is related to APIv2 and should not break APIv1.
Proposed change¶
This change proposes to remove job binary internal in favour of other storage options. Planning to deprecate it when APIv2 is stable, in tandem with a deprecation of APIv1. Both APIv1 and JBI will be fully removed together after APIv2 has been stable for long enough.
This change can be divided in the patches below.
remove job binary internal from APIv2
remove internal code that deals with job binary internal (possibly a few patches)
remove job binary internal from database
remove job binary internal from saharaclient
remove job binary internal option from Horizon (sahara-dashboard)
update documentation involving job binary internal
Alternatives¶
Another option for this change would be not remove job binary internal, which could bring future problems to Sahara.
Data model impact¶
Job binary internal will be removed from the data model. This will require a database migration.
REST API impact¶
Job binary internal related requests must be removed only in APIv2.
Other end user impact¶
Job binary internal option should not be available through Horizon.
Deployer impact¶
None
Developer impact¶
None
Sahara-image-elements impact¶
None
Sahara-dashboard / Horizon impact¶
Job binary internal option should not be available through Horizon.
