memory for annotations unless actually required.
> unnecessary copying of date for message on many queues

> The memory used when sending messages to a large number of queues is higher
> than it needs to be as only the data as read of the wire is shared. The
> memory used can be reduced by sharing some of the essentially immutable state
> computed before enqueing.
