----------------------------------
Summary: Change the default output file
Key: TAJO-1340
URL: https://issues.apache.org/jira/browse/TAJO-1340
Project: Tajo
Issue Type: Improvement
Reporter: Hyunsik Choi
Fix For: 0.11
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.
