> When repair a table with thousands of partitions, it could take hundreds of seconds, Hive metastore can only add a few partitioins per seconds, because it will list all the files for each partition to gather the fast stats (number of files, total size of files).
> We could improve this by listing the files in Spark in parallel, than sending the fast stats to Hive metastore to avoid this sequential listing.
