The DataStore component in my AGE 10.7 install has the Tile Cache enabled, but it appears to do nothing. I was able to log in to the REST interface on port 29080 and I can see one database called dsconfig$ with a copy of the datastore config in it, and nothing else.
When I poke around on my server's filesystem I can see that it appears to store the tile caches I create in the filesystem in "bundle" files, not in the Tile Cache.
Do I just have the wrong idea about what the DataStore Tile Cache is for?
Perhaps ESRI decided that filesystem / bundle files are superior?
