> 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
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.41.0

> Because the "getFDs" method 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.
