[~julianhyde] Thank you very much for your reply. The question you raised is
one I've been thinking about. Coming up with a good name is indeed difficult.
I'm constantly thinking about this. I'm currently refactoring this part of the
logic. If you have any suggestions or comments, please feel free to let me know.
> Implement Core FD Algorithm Library for Functional Dependencies
> ---------------------------------------------------------------
>
> Key: CALCITE-7205
> URL: https://issues.apache.org/jira/browse/CALCITE-7205
> Project: Calcite
> Issue Type: Task
> Components: core
> Affects Versions: 1.40.0
> Reporter: Zhen Chen
> Assignee: Zhen Chen
> Priority: Minor
> Labels: pull-request-available

> 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].
