>          Components: hive-registration

> Currently, we compute a diff between the current partition and an already 
> registered partition when a partition has already been registered in Hive. 
> This is done by calling getPartition() on the Hive metastore client, which 
> can be expensive. Since no time-varying attributes are stored in a Hive 
> partition, diff computation (and getPartition() call) can be skipped when a 
> partition already exists.
