>
> MV updates are currently completely asynchronous in order to provide 
> parallelism of updates trying to acquire the partition lock. For some use 
> cases, leaving the MV updates asynchronous is exactly what's needed.
> However, there are some use cases where knowing that the update has either 
> succeeded or failed on the view is necessary, especially when trying to allow 
> read-your-write behavior. In those cases, we would follow the same code path 
> as asynchronous writes, but at the end wait on the acknowledgements from the 
> view replicas before acknowledging our write. This option should be for each 
> MV separately, since MVs which need the synchronous properties might be mixed 
> with MV which do not need this.
