mahesh kumar behera commented on HIVE-25540:
--------------------------------------------
[~zabetak]
The batch update uses direct SQL to optimize the number of backend database
calls. Some of the SQL used are not supported by Oracle. So we need to put a
check to go via DN if the backend DB is Oracle. Currently we have tested only
in Mysql and Postgres. Batch update feature is not yet shipped.
> Enable batch update of column stats only for MySql and Postgres
