          Issue Type: Improvement
            Reporter: xuchuanyin
            Assignee: xuchuanyin


We need to record more detailed information during carbondata processing (query & load).

These information can be used:
 # for figuring out the possible performance problems in carbondata
 # for tuning
 # as input for some adaptive strategy

Here are some examples:

For data query:
 # Time costs for sql parse/optimize/plan
 # Time to load&read metadata
 # Time to schedule
 # Time to execute
 # ...

For data loading:
 # Time to schedule
 # Time to execute
 # Disk spill amount
 # ...
