Remove Job Binary Internal

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.
