> Key: TAJO-1340
> URL: https://issues.apache.org/jira/browse/TAJO-1340
> Project: Tajo
> Issue Type: Improvement
> Components: Java Client, JDBC Driver, Offheap, Storage
> Reporter: Hyunsik Choi
> Assignee: Jinho Kim
> Fix For: 0.11.0, 0.12.0
>
> Attachments: TAJO-1340.patch, TAJO-1340_2.patch
>
>
> 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.
