sphere already have its own LIST function to create "virtual" arrays with basic functions like insert/remove/sort values, if you just need some simple storage maybe it will work. But honestly I never used it so I don't know if its safe to use on scenarios like 8500 lines loop

as Ben said, if you need something local and a bit more complex you can use sphere internal SQLite engine. Or if you need something even more complex you can install an MySQL server to use advanced SQL commands, create more SQL users, access it remotely, etc
