> In current scenario, to add partitions for external tables to metastore, MSCK 
> REPAIR command has to be executed manually. To avoid this manual step, 
> external tables can be specified a table property based on which a background 
> metastore thread can sync partitions periodically. Tables can also be 
> specified with partition retention period. Any partition whose age exceeds 
> the retention period will be dropped automatically.
