> 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.
