> In Hive, we can create bucket tables, divide data in fine-grained ways, and publish data to different files based on bucket columns. Like this, we can make specific optimizations to the Query to speed up the Query. 
> I think it would be exciting for Impala to have support for bucket table creation and related optimizations.
> The following document is a design document that supports the creation of bucket tables. If you are interested,  welcome to give some suggestions.
