Subject: Re: [controller-dev] TransactionChain
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.

Can’t it be solved with this code? (Pseudo code)
AsyncWriteTransaction t1 = broker.newWriteOnlyTransaction();
t1.put(id, data);
Future f = t1.submit();
Futures.addCallback(new Callback{
AsyncReadTransaction t2 = broker.newReadOnlyTransaction();
Optional<?> maybeData = t2.read(id).get();
}
Thanks,
