I forgot what the deal is with
TransactionAbortedError; when the (KV) client receives this error, does it need to do cleanup by sending an
commit == false, or is there nothing to cleanup? In other words, does the
Transaction proto that the client get back have the same
ID (and an incremented epoch) or newly generated one? I’m guessing it’s the same ID, so as to keep the old intents in place, but then I’m not sure what the difference is between this aborted error, and any other retriable errors? Do other retriable errors no increment the epoch?
Also, I’m having a bit of trouble finding the code that does the relevant manipulation of the
Transaction proto in case of this error. Does it happen client-side, in
TxnCoordSender, or server side by attaching an updated txn proto to a
