------------------------------------------
> Support extraction of replication spec from notification event.
> ----------------------------------------------------------------
>
> Key: HIVE-21770
> URL: https://issues.apache.org/jira/browse/HIVE-21770
> Project: Hive
> Issue Type: Sub-task
> Components: HiveServer2, repl
> Affects Versions: 4.0.0
> Reporter: mahesh kumar behera
> Assignee: mahesh kumar behera
> Priority: Major
> Fix For: 4.0.0
>
>
> The notification event structure currently does not have the partition spec.
> Events which can span across multiple databases and tables, the database and
> table info can not be obtained from the event structure. To know the event is
> added for which partition, the event message has to be deserialized and the
> partition information can be obtained from it.
> * Each event handler has to expose a static API.
> * The API should take the event as input and return the list of db name,
> table name and partition spec from it.
> * If database name, table name or partition name is present in the event
> structure, then return it. If all these info are present then no need to
> deserialize the message. Later if these info are added to the event structure
> then it will be useful.
> * Deserialize the message and create the list of name and return through a
> partition info class object.
> * If the table is not partitioned or is table level event, then set the
> partition info as null. Same for table info incase of db level events.
