This project don't have some .avro or .txt files when aggregating a cube using n-dims.
So I dont know how to create a .avro file and organize the data structure.
Can you upload some files as demo, to show the inner data structure in the .avro file?

Thanks a lot!

Hi Theseus,

Under release folderhttps://github.com/linkedin/Cubert/tree/master/release we have provided a simple word count example with text input. With the following releases, we will try to add an example with AVRO and possibly one using CUBE. In the meantime, you could use any standard avro file in cubert script (you could also use the sample ones in Apache Avro download).

You can see code snippets and how to use CUBE statement with different options in the documentation—specifically look at these topics: Aggregation: Cube and Grouping Setshttp://linkedin.github.io/Cubert/concepts/grouping_sets.html?highlight=cube and Aggregation Operators:Cubehttp://linkedin.github.io/Cubert/operators/aggregation.html?highlight=cube.

Thanks,
mani
