Aihua Xu commented on HIVE-16912:
---------------------------------

So this property is new which should be set in order to take advantage of the 
performance benefit?

Since we have the connection URL to the database like 
{{javax.jdo.option.ConnectionURL: jdbc:oracle:thin:@saturn:1521:solarsid}}, 
probably we can automatically get the database name?

> Currently, this validator uses DatabaseMetaData.getTables() that takes in the 
> order of minutes to return because of the number of SYSTEM tables present in 
> Oracle.
> Providing a schema name via a system property would limit the number of 
> tables being returned and thus improve performance.
