### What changes were proposed in this pull request? 1, optimize `predictQuantiles` by pre-computing an auxiliary var. ### Why are the changes needed? In https://github.com/apache/spark/pull/30000, I optimized the `transform` method. I find that we can also optimize `predictQuantiles` by pre-computing an auxiliary var. It is about 56% faster than existing impl. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? existing testsuites Closes #30034 from zhengruifeng/aft_quantiles_opt. Authored-by: zhengruifeng <ruifengz@foxmail.com> Signed-off-by: Sean Owen <srowen@gmail.com> |
