Is there a ParallelWriter for DynamicBuffers?

NativeList has a method AsParallelWriter() while I don't see one for DynamicBuffers. I want to be able to add items to it in parallel. I guess a rephrase of the question is can I add items to DynamicBuffers in parallel? Is that safe?

 

Nope. But you can for example resize Dynamic buffer prior parallel job, then write to the buffer in the parallel, with no size change.

 

You can also use EntityCommandBuffer.ParallelWriter.AppendBuffer(). Though I wouldn’t recommend it unless there weren’t other options.

Preallocating your DB to the max size you need, and then writing to it in parallel from multiple jobs (assuming none of those jobs ever touches the same index in the DB), is usually a better way to go.
