Azure Cosmos DB Core (SQL)

• 首先要有cosmos db的account
• 然后才可以生成cosmos db，默认throughput是4000(而且4000是最小值)，自动调整从10%(即400 RU/s)开始。

  Your container throughput will automatically scale from 400 RU/s (10% of max RU/s) - 4000 RU/s based on usage.

• 然后生成container，相当于传统数据库表的表，container共享db的throughput。

代码生成cosmos db.
