             Summary: Enhance Functional Dependency Computation Performance 
Through Advanced Caching Mechanisms
                 Key: CALCITE-7219
                 URL: https://issues.apache.org/jira/browse/CALCITE-7219
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.40.0
            Reporter: Zhen Chen


Because the "getFD" smethod exists outside the metadata API framework, it 
cannot leverage the existing caching infrastructure. Each invocation triggers a 
full recomputation, and this may occur repeatedly within a single metadata 
query operation. This architectural gap poses a serious performance risk.​
