> 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.
