This enhances failover safety and data durability for high-availability clusters.

Declarative Foreign Data Management

We introduced comprehensive declarative management for Foreign Data Wrappers (FDW) by extending the Database CRD. This feature adds the .spec.fdws and .spec.servers fields, allowing you to manage FDW extensions and foreign servers directly from the Database resource.

This work was implemented by Ying Zhu (@EdwinaZhu) as part of the LFX Mentorship Program 2025 Term 2.
