Snowpark的核心概念是DataFrame(数据框),它表示一组数据,就比如说一些数据库表的行,我们可以用最喜欢的工具通过面向对象或者函数式编程的方式处理。Snowpark DataFrames的概念类似于Apache Spark或者Python中Pandas包的DataFrames的含义,是一种表格型的数据结构。 开发者也可以创建自定义函数推送到Snowflake服务器,来更方...

none of the complexities. The Snowpark framework brings integrated, DataFrame-style programming to the languages developers like to use and performs large-scale data processing, all executed inside of Snowflake. Here are just a few of the things that organizations are accomplishing using Snowpark. ...
