> I need all possible mutations to be able to be bundled into a generic batchMutation, and sent as one operation.
> In the absence of database constraints, this gives you all the benefits of transactions with none of the implementation pain. All I care about is whether a bundle of updates reaches the server atomically, mitigating issues with unreliable client VMs, and allowing the client to "roll back" a set of operations by merely discarding the batch.
