Utilities.constructVectorizedReduceRowOI介绍

[英]Create row key and value object inspectors for reduce vectorization. The row object inspector used by ReduceWork needs to be a standard struct object inspector, not just any struct object inspector.
[中]创建行键和值对象检查器以减少矢量化。ReduceWork使用的行对象检查器需要是标准结构对象检查器，而不仅仅是任何结构对象检查器。
