Five migration down functions were broken, causing the SQL report to flag
them as not reversible. All issues were pre-existing bugs that were never
caught because the down migrations had never been exercised under the
reversibility checker.
- 20241003170511: add .notNullable() to both up and down when altering
locations.target, preventing the NOT NULL constraint from being silently
dropped by knex's .alter() when widening varchar(255) to text.
- 20220116144621: implement a real down function that recreates the three
dropped legacy tables (entities, entities_search, entities_relations)
with correct columns and indices.
- 20210302150147: drop dependent tables in the correct order to avoid a
FK constraint violation, and fix a typo (references → refresh_state_references).
- 20201005122705: drop full_name from entities (not entities_search), and
restore entities_unique_name with the correct column order (kind, name, namespace).
- 20200702153613: use table.integer('generation') instead of table.string()
in the down function to restore the correct column type.

What is Backstage?
Backstage is an open source framework for building developer portals. Powered by a centralized software catalog, Backstage restores order to your microservices and infrastructure and enables your product teams to ship high-quality code quickly without compromising autonomy.
Backstage unifies all your infrastructure tooling, services, and documentation to create a streamlined development environment from end to end.
Out of the box, Backstage includes:
- Backstage Software Catalog for managing all your software such as microservices, libraries, data pipelines, websites, and ML models
- Backstage Software Templates for quickly spinning up new projects and standardizing your tooling with your organization’s best practices
- Backstage TechDocs for making it easy to create, maintain, find, and use technical documentation, using a "docs like code" approach
- Plus, a growing ecosystem of open source plugins that further expand Backstage’s customizability and functionality
Backstage was created by Spotify but is now hosted by the Cloud Native Computing Foundation (CNCF) as an Incubation level project. For more information, see the announcement.
