Well, a part of my tool are libraries of tiles. Support for enormous libraries of tiles. A lot of them and them being quite large.
But these libraries need to be properly managed, take up minimum disk space and be quick to access. So, having something SQLite to manage those, seems like a good idea. I embed binary blobs of Flatbuffers in the sqlite files, where the access for anything under 100kb in size is more performant than flat disk reads, since you don’t have to request as much from the OS, since you are just dealing with a lot fewer files.
