write, to the database, the identified rows based at least in part on the first timestamps of the written rows being later than the respective second timestamps for the corresponding rows in the database.

12. The system of claim 11 , wherein, to write the downloaded metadata to the database, the management system is further configured to:

determine, for the identified rows, whether values in the identified rows are different than values in the corresponding rows in the database, wherein the written rows being written to the database is further based at least in part on the values in the written rows being different than the values in the corresponding rows in the database.

13. The system of claim 6 , wherein, to write the downloaded metadata to the database, the management system is further configured to:

determine, for rows of the one or more metadata tables, whether respective version numbers match a version number of a loading job for writing the respective metadata for the data management cluster to the database, the respective version numbers corresponding to a version number of a prior loading job; and

write, to the database, rows of the one or more metadata tables for which there is a mismatch with the version number of the loading job.
