We have a problem setting up the GeoServer for a specific scenario: in total we have more than 12.000 images (in COG format, located in s3 bucket) that shall be published as WMS service. The images cover different spatial and temporal extents - the resulting WMS should have the full extent. Unfortunately it seems that GeoServer is not capable of handling a bucket with many files. We checked the COG module, but it is only possible to have one single file as input data. Please note that we are using the GeoServer Cloud version as we are running in a cloud environment.
Are there any ideas how to set up the WMS? Would an Image Mosaic be the right way to do this? Do you have any suggestion regarding our approach?
