https://www.infoq.com/podcasts/aws-lambda-custom-database-retriever they use lambda and do not do indexing

And in particular, we only read at query time, we don't do any aggregation or indexing, even calculated columns are all done at query time. So we wind up being compute bound. It's not even network incoming read data. It takes a lot of CPU to read all this data and run your query over it.

之前我想过怎么表达一个函数的“color” 就是可以通过调用链传染的性质，比如const async 这些。还可以自己发明性质来保障一些业务安全。后来我学习了这个东西叫做effect system。

rust正在搞一个青春版effect system。我觉得要是能搞出完整的可自定义的effecr比较好，但是他们好像要搞一个有限制版本的，只支持rust keywords 的effects
