Shared Dyamic Buffers?

Is it possible to have a dynamic buffer we a shared component?

I'm trying to store some animation data in a dynamic buffer (each item being an "Animation Clip"), and since multiple entities will use the same animation data, is there a way to have this dynamic buffer also be shared data?

 

Blob arrays are what you are looking for https://docs.unity3d.com/Packages/com.unity.entities@0.1/api/Unity.Entities.BlobArray-1.html.

I see that you are working with animations. According to the Unite Copenhagen keynote a DOTS animation preview package will be available with 2019.3. What about Playable API?
