Zhen Chen updated CALCITE-7205:
-------------------------------
Description:
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, 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].
