Athena

Possibly using athena instead of or ontop of open search for route discovery. I think for now going with open search but research should be done on athena to see what advantages it might have in comparision to open search.

Athena has a rest api:

Queries can be executed and generate output to a dedicated s3 bucket. So in theory each time a panel page is created the routes could be recreated using athena and dumped to s3. I think they could than be loaded as a single document of json objects or as a csv file in the browser to do the route matching.
