I have a large dataset that I may want to publish as a hosted layer in ArcGIS Online. The source file geodatabase containing the single source feature class is approx 5 GB in size. However, when I published this as a hosted feature layer (from ArcGIS Pro 3.3.1), the resulting size of the feature layer was reported as approx 21 GB.
Note that this is a basic read-only feature layer with no sync, no editor tracking and no attachments, so I am trying to understand why the resulting feature layer is so much bigger than the source FGDB.
Obviously there is a huge difference in storage credit consumption between 5 GB (approx 1200 credits) and 21 GB (approx 5000 credits).
Can anyone explain why the published feature layer is 4x larger than the FGDB? Has anyone else experienced similar?
I would expect some difference due to different storage formats, but not 4x difference!
