>
> 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.
