[AttributeUsage(AttributeTargets.Parameter)]
public sealed class EntityIndexInQuery : Attribute, _AttributeRemarks
This is generally way more expensive than ChunkIndexInQuery and EntityIndexInChunk. As it it will schedule a CalculateBaseEntityIndexArrayAsync(AllocatorManager.AllocatorHandle, JobHandle, out JobHandle) job to get an offset buffer. If you just want a sortkey for your EntityCommandBuffer.ParallelWriter simply use ChunkIndexInQuery as it is different for every thread, which is all a ParallelWriter needs to sort with.
