EnTT and multithreading

[Lumengine]

Hi,
I'm using EnTT as the main representation of my scene for 3D simulations. I’d like to multithread scene modifications. Let’s say I have many worker threads that may need to modify any component in the registry.

How would you approach this?

I’ve already protected entity creation, but when it comes to modifying the registry, I was thinking about using a queue of commands that are dequeued and executed on a single thread. However, this could result in a large number of small lambdas that might hurt performance.

I also heard about using a local registry per thread that gets merged back into the main one at the end of the frame. Is that a viable approach?

I’d be happy to get any feedback on this.
Thanks,

Baptiste
