> Reporter: Hyunsik Choi
> Assignee: Jinho Kim
> Fix For: 0.11.0
>
>
> Currently, the default output file is CSV. Due to its nature, CSV has mainly
> three problems:
> * Its line or field delimiter can be duplicated to some character included
> in the result data.
> * Plan text file is likely to be larger than other file formats.
> * Its read and write performance is slow.
> We need to change the default output file format into other file formats. We
> also need to investigate which file format is the best for it.
