Minimizing build times for enormous projects

For a game that will get absolutely enormous, is there a way to just build a part of the catalog instead of the whole thing (and still have the catalog.json be correct for the whole)?
Maybe it actually already does this (e.g. does not rebuild asset bundles that don't need it)? If so how does that work and how can we best setup our addressables to minimize our build times?

Clarification edit -- We don't intend to do content updates. We would always be deploying the game as the whole game build. We just want making a game build to be fast or potentially able to be broken up into chunks depending on what changed.

Thanks

 

Also interested in this; our 5GB builds (hardly enormous, imo) take around ~2hrs (with caches).

 

Have you turned off Optimize Mesh Data in Project Settings?
If you haven't done it already, it can speed up builds quite a bit assuming such optimizations are not crucial to you. And I am not convinced it does anything when run as part of the addressables build. The resulting bundles were the same size for our project.

 

If multiple catalog.json are fine - you could try building separate packages as described in https://forum.unity.com/threads/modding-with-addressables.539926/#post-5355612. Then you can load/unload them runtime but initial setup may be slightly difficult.

Maybe content update only build part of catalog? Haven't tried that feature yet.

 

Thank you for the tip, but looks like it is already disabled on our project.
