> Resource calculator currently considers only cpu and memory. However, disk is 
> an important resource in the first stage, so should be considered for 
> available resource calculation.
> In addition, in the current implementation, a worker sends a heartbeat 
> whenever it finishes processing half of the assigned tasks. So, the problem 
> of ignoring disk resource makes the first heartbeat delayed during the first 
> stage, thereby making the query execution slow.
