saving dask dataframe in bcolz format

Question

The dask documentation states: "BColz is an on-disk, chunked, compressed, column-store. These attributes make it very attractive for dask.dataframe which can operate particularly well on it. There is a special from_bcolz function."

However, I could not find an example how to save a dask dataframe to bcolz. What is the recommended way to do this?

我创建了一个拉取请求来实现它。在它合并到主分支之前，你可以在这里找到它：

如果您不想编辑自己的Dask实现，只需复制TConfigData方法即可。
