I assume you mean:
Future *f* = t1.submit();
Futures.addCallback(*f*, new Callback{
AsyncReadTransaction t2 = broker.newReadOnlyTransaction();
Optional<?> maybeData = t2.read(id).get();
}
yes that would accomplish the result that the TransactionChain provides.
But with TransactionChain, you don't have to wait for the write to be
committed - you can read it immediately after submitting. Also makes the
code simpler.
