I often compress file geodatabases to reduce data volume for static datasets. I am also being supplied , in ever increasing regularity datasets supplied as geopackages. When I import such data into a file geodatabase it takes on the field formats but the compression tool errors with this message:
ERROR 161003: Cannot compress ea_detailed_watersheds. Compression not supported on 64-bit object ID, big integer, date only, time only or timestamp offset fields.
So my idea is to update the compression tool to work with 64-bit object ID, big integer, date only, time only or timestamp offset fields as these will become increasingly more common.
