Increase in size of hosted feature layer published from FGDB

JohnFannon — Mon, 19 Aug 2024 15:06:11 GMT

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!

Were you able to find out anything about this? I have a user who published a hosted feature layer that is consuming 1.7GB of space. When I download a copy as a FGDB it's around 367 MB.

Is there an update on this? I published a FGDB that was 1.1 MB. But post publishing, the hosted feature layer size is 220 MB: a 200x improvement in size!
I published another FGDB that was 1.8 MB, which published to 60 MB.
