NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

对数据帧进行比较是数据工程中的常见任务，常用于确保两个数据转换方法间没有显著的偏差或不一致。 DataComPy 是一个用于比较 pandas, Spark 或其他格式 DataFrame 的工具。这个库不仅能比较 DataFrame 的一致性，还能在行和列上对不一致的地方给出细致的洞见。 DataComPy 还可以指定忽略掉无需展示的数值绝对/相对比较和已知差异。我们的一些团队将它用于了冒烟测试组件中，他们发现它能高效比对大数据量多字段的 DataFrame，与此同时它给出的报告也易于理解和应对。
