> This JIRA primarily provides foundational capabilities for *relational
> algebra and metadata reasoning*.
> *Main Implementations:*
> * Encapsulates functional dependency (FD) sets, supporting basic operations
> such as addition, deletion, and query.
> * Provides algorithms for closure computation, minimal cover, equivalence
> judgment, and candidate key discovery.
> * Supports efficient attribute reasoning and dependency reasoning,
> facilitating use by upper-layer optimizers and metadata modules.
> Please refer to the discussion in the PR for [more
> details|https://github.com/apache/calcite/pull/4540#discussion_r2384265382].
