----------------------------------
Summary: 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
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.
