"Nuke version" to simplify data model changes during development

For renames and type changes, there is an UID-based approach to work with already deployed databases.

However during development, it may just be easier to wipe all data and model data.

API outline:

MyObjectBox.builder().version(7).nukeDataBeforeVersion(7)

Thus, ObjectBox would track the current version of the data model, and just discard everything for earlier versions.

Alternative API: annotations, but where to apply them? Also the builder seems appropriate because that's where the initialization happens.

Looking into the future, this approach should also work nicely with custom migration callbacks. E.g.

MyObjectBox.builder().version(10).nukeDataBeforeVersion(7).migrate(new MyMigration())

Here, versions 1 to 6 just would be nuked, and version 10 would be applied. For versions 7 to 9, the custom migration would be triggered.

Feedback on this approach welcome!

Non viene indicato alcun file o test; inizia esaminando il percorso di inizializzazione di MyObjectBox.builder() e il modo in cui vengono tracciate le versioni del modello dati. Definisci l'API e il comportamento per scartare i dati delle versioni precedenti, mantenendo la gestione personalizzata delle migrazioni proposta per le versioni successive.
