> Project: Tajo
> Issue Type: Improvement
> Components: query master
> Reporter: Jihoon Son
> Assignee: Navis

> Currently, Tajo can execute ExecutionBlocks one by one even though there
> remain enough resources to execute two or more ExecutionBlocks.
> We can improve the query processing performance by executing two or more
> independent ExecutionBlocks if possible.
