--------------------------------------------


> Support External only tables for particular databases.

>                 Key: HIVE-25724
>                 URL: https://issues.apache.org/jira/browse/HIVE-25724
>             Project: Hive
>          Issue Type: Improvement
>          Components: HiveServer2, Standalone Metastore
>            Reporter: Sai Hemanth Gantasala
>            Assignee: Sai Hemanth Gantasala
>            Priority: Major
>
> Goal:
> To be able to support disabling of ACID tables for a particular database.
> Why?:
> There is a use case to support BDR and hive3 replication engines in parallel. 
> This can be used to avoid the creation of ACID tables in DBs replicated by 
> the BDR engine. (BDR does not have the ability to replicate ACID tables)
> Some users might want to use this as well for their legacy DBs while they 
> transition to ACID tables in some newer DBs.
> How?
> A "special" property to be set on the database. If this property is set, HMS 
> will prevent the creation of ACID tables in this database.
> Note:
>  # Hive/HMS to implement the enforcement of this property in preventing table 
> creation.
>  # Hive/HMS will not prevent end-users from setting/tampering with this 
> property.
