• Setup an Image service with RDS as back end.
• The image service is pointing to the mosaic dataset sitting into the RDS.
• Set up a GP service which is secured one.
• This GP service takes the input mrf string and does the add raster operation on the mosaic directly

Daily process

• A new file comes in the s3 bucket,
• A lambda process kicks in, which connects to the GP service
• This GP service takes an input as the MRF string and executes its. ( since this is a rest call it does not need any other dependency)
• The newly added data gets reflected can be done using the refresh service option (https://developers.arcgis.com/rest/services-reference/refreshservice.htm)

There is no such documentation on this, but we have used this a few times before.

Other option is to have separate ec2 machine which does the add raster operation. We can talk about all these options in the call sometime.

Regarding the update for the issue reported, I have sent a reply to a different thread. I have also updated the Git repository with the changes.
