I guess I was following the example in on this page: https://mapserver.org/mapcache/caches.html (https://mapserver.org/mapcache/caches.html)
It explains the naming. Look under section: Using Multiple SQLite Database Files. You don't need to worry about calling the database. Mapcache is doing that. /Lars Schylberg September 20, 2018 2:40 PM, "Sebastiano Laini" <[email protected] (mailto:[email protected]?to=%22Sebastiano%20Laini%22%20<[email protected]>)> wrote: Thanks guys, I will try to do it after I will recompile again Mapcache to use SQLite as I compite it -DWITH_SQLITE=OFF I suppose that I can also think about to split the db as we are speaking about more than 10milion files. How exactly do you call the database and how this code /{grid}/{tileset}/{z}/{x}-{y} works?

So seeding a large area You end up with many sqlite db files that all work together. This has worked really good for our use case.

I was thinking to propose to my supervisor to use the “SQLite Caches” but I don’t know how it works. Can someone guide me through the process of setup MapCache with this type of cache? And if I need some dependency, we use PostgreSQL in our server so I assume I need to install also MySQL. I’ve already read the documentation but still I have doubt about the db part, how to create the db and locate it. I never use SQLite, just PostgreSQL.
