const MIGRATION_VERSION_KEY: &str = "migration_version";Expand description
Catalog key of the migration_version setting.
The migration_version tracks the version of the binary that last successfully performed and
committed all the catalog migrations (including builtin schema migrations). It can be used by
migration logic to identify the source version from which to migrate.
Note that the durable catalog also knows a catalog_content_version. That doesn’t work for
this purpose as it is already bumped to the current binary version when the catalog is opened
in writable mode, before any migrations have run.
