Batch / Prefetch / Despawn Systems

[nixpulvis]

• So I guess I may need yet another layer between the game engine and the DB, so I can make an expensive query, then chunk up the result and load it in batches. This probably means we move to fetching and spawning in cubes (the spyglass will still be a sphere though)

See E:D’s loading batched 50Ly cubes:

• Additionally, we should predict motion of the spyglass and try prefetching stuff. We could start by always fetching just a bit more than the spyglass radius.

• Finally, stuff outside of the spyglass for a while should be despawned.
