问题描述

What is the maximum column count of spark Dataframe? I tried getting it from data frame documentation but unable to find it.

推荐答案

从体系结构的角度看，它们是可伸缩的，因此列数不应有任何限制，但会导致节点和负载的负载不均. ;可能会影响转换的整体效果.

From the architectural perspective, they are scalable, so there should not be any limit on the column count, but it can give rise to uneven load on the nodes & may affect the overall performance of your transformations.
