> Won't have time for parent. But a deferred sync option on a per operation basis comes
up quite frequently.
> In 0.96 this can be handled cleanly via protobufs and 0.94 we can have a special mutation
attribute.
> For batch operation we'd take the safest sync option of any of the mutations. I.e. if
there is at least one that wants to be flushed we'd sync the batch, if there's none of those
but at least one that wants deferred flush we defer flush the batch, etc.
