Cheng Hao commented on HIVE-4410:
---------------------------------

for example:

CREATE TABLE dummy_uservisits (sourceIP STRING,destURL STRING,visitDate 
STRING,adRevenue DOUBLE,userAgent STRING,countryCode STRING,languageCode 
STRING,searchWord STRING,duration INT) STORED BY 
'org.apache.hadoop.hive.ql.metadata.DummyStorageHandler';

insert overwrite table dummy_uservisits select * from uservisits where 
(xxxxxxx); 

No real data be written into the dummy table, and great helpful in benchmarking 
the "Select" performance.

> Create a Dummy Storage handler for the "select" performance benchmarking 
> purpose, without real data output(write to the console or disk). It's would 
> be great helpful if the result is "big".
