Dear experts, The question is related to how to trigger loading data in the backend for a geoserver map using curl.
Background: I am working with geoserver with geomesa/hbase data. I typically work with a small number of maps. Caching is very important: cold data takes much longer to load then hot data. In my startup script for geoserver (=shell), I would like to completely load my maps once (while getting a coffee-takes 20 minutes combined) before I really start my analysis (during the real analysis I zoom in, out, move, apply CQL filters) so they are in the cache-makes using it a lot more pleasant. When I load a map in the browser, I can see in the geoserver logs the query plan, then I see in my back-end (hbase) heavy loads going on, and caching happens, and after a while the map shows up. But when I curl from a shell to get the map: curl "http://server:port/geoserver/cite/wms?service=WMS&version=1.1.0&request=GetMap&layers=map1,map2&CQL_FILTER=query1,query2&styles=polygon,heatmap&width=768&height=384&srs=EPSG%3A4326&format=application/openlayers<https://server:port/geoserver/cite/wms?service=WMS&version=1.1.0&request=GetMap&layers=map1,map2&CQL_FILTER=query1,query2&styles=polygon,heatmap&width=768&height=384&srs=EPSG:4326&format=application/openlayers>” I see in the geoserver log I see the getMap response immediately (impossible that the data really started loading in the back-end), and in hbase I can see that he did not start reading the data so the cache is not laded. The map really is loaded through open layers, maybe there is something else I should trigger in my shell, besides the curl command? Thanks for input!
