If the catalog is in Online mode, updating the catalog obtains any new patches or modifies existing patches that have changed. To prevent new patches from being downloaded, do not run the Catalog Update Job until you need new patches in the catalog.
If the catalog is in Offline mode, then to prevent new patches from being downloaded, you must ensure:
- The source location has not been updated by re-running the downloader
- The metadata file(s), if applicable, in the depot have not been changed since the last run
If you ensure the preceding items, running a Catalog Update Job does not add any new patch metadata or modify existing patch metadata.
