> With Recon’s new schema versioning framework now integrated HDDS-11465, it is essential to address initial schema constraints for existing tables. Previously, Recon lacked schema versioning, which meant there were no upgrade actions or mechanisms to adjust schema tables post-upgrade. This led to inconsistencies, especially when new enum states (like {{MISSING}} and {{NEGATIVE_SIZE}} in {{{}UnHealthyContainerStates{}}}) were introduced, as older schema versions might still persist despite upgrades.
> This ticket introduces a foundational upgrade action, {{{}InitialConstraintUpgradeAction{}}}, associated with the *INITIAL_VERSION* feature to handle any missed schema updates within the {{UNHEALTHY_CONTAINERS}} table. This upgrade action retroactively applies constraints and ensures all existing tables are correctly versioned. Moving forward, any updates or new metadata table introductions in Recon will be tracked and managed by version using the {{ReconLayoutFeature}} framework, enabling a structured upgrade process for future schema changes
