SpacetimeDB supports for hashmap indexing

Hey @vovacooper! Can you help us understand why this is so important for you?

hello @bfops !
i personally would love this feature to be able to find data (like vector3) in O(1) time for my voxel world.

Hey @Frisk197! I can say that BitCraft is currently using btree indexes for their world, and it's working well for them (on top of chunking, similar to what Minecraft does).

Are you seeing performance issues in your project?

@bfops
yes i do have a performance issue, but i'm not sure if it's some limitation of spacetimedb or my dogshit code X)

I'm trying to send a list of 10 positions to the server every 100ms.
it's supposed to do a fast voxel traversal from the origin of the scan to all the points to remove any points in between and then add the point to the database but sometimes it can take 4 seconds for some reason.

here's a test repository with some parts of my project to reproduce the problem : https://github.com/Frisk197/SaKADo_TEST
i'm making an xr app but with this setup you can just start the app in unity

i was asked on the discord to make a new issue : https://github.com/clockworklabs/SpacetimeDB/issues/3394
