zhengruifeng opened a new pull request, #58109: URL: https://github.com/apache/spark/pull/58109
### What changes were proposed in this pull request? Change tree model `leafAttr` from a `lazy val` to a `def`. `leafAttr` is a small metadata object derived from `numLeave`, and `numLeave` remains cached. ### Why are the changes needed? `leafAttr` is only used when building leaf-column schema metadata. Since the expensive leaf count is already cached by `numLeave`, caching the derived attribute itself is unnecessary. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Ran: ``` build/sbt -java-home /usr/lib/jvm/java-17-openjdk-amd64 mllib/compile ``` ### Was this patch authored or co-authored using generative AI tooling?
