我一直在努力争取这一天约一天.我正在直接测试Azure Blob存储上传并获得可怕的CORS问题."XMLHttpRequest cannot load https://tempodevelop.blob.core.windows.net/tmp/a4d8e867-f13e-343f-c6d3-a603…Ym0PlrBn%2BU/UzUs7QUhQw%3D&sv=2014-02-14&se=2016-10-12T17%3A59%3A26.638531.

我需要对数据运行多个测试以查找异常和模式。我希望该实用程序是某人可以下载而不必安装或配置的东西。
是否有关于 NoSQL 或 SQL 数据库的建议,我可以在内存中启动它,将 CSV 加载到表中,然后针对该数据运行查询?
Redis可以不用安装吗?还有什么?
