In Datomic Cloud, can a d/with operation be performed by any node? Any node in the PCG? Or only on the current transactor? Essentially this informs a design decision of running a speculative sequence of transactions on an arbitrary node versus running it in a transaction function...

d/with operates on a database, so no transactor is required

OK. That implies that any transaction functions must exist on the invoking node as well -which is really important to keep in mind. Thanks!

Understanding this answer also seems relevant for exploiting hints when they are made available on DC.
