cete's Issues

warning with `table.CountBetween`

Many warnings appear, from use of this function:

cete/count_test.go

E.g.:

A .sst file is created every time Cete is opened

第一次尝试， 发现一个问题（也可能姿势不对）

运行了那段示例的代码
上图的代码中，每次执行Open，就会多一个 .sst 文件
不太理解这是为什么

I'm using Cete for the first time, and I seem to be running into a problem (although I might be doing something incorrectly).
If you run the example code (in the README) you will find that every time Open is called, a new .sst file is created.
It isn't clear why this is so.
