> When partitions are tracked by the catalog, that will compute all custom
> partition locations, especially when dynamic partitions, and the field
> staticPartitions is empty.
> The poor performance of the method listPartitions results in a long period
> of no response at the Driver.
> When read 12253 partitions, the method getPartitionsByNames takes 2 seconds,
> and the getPartitions takes 457 seconds, nearly 8 minutes
