queue - rabbitMQ persistency when consummers die -

-

i consummers subscribe events, in case 1 of them die, i'd messages persisted consummer, gets them once online. if producer creates n queues, 1 per consummer, works. producer shall not not take care of whether there consummers or not, , how many are. consummer shall have responsibility create own queue, select messages wants receive, , queue shall persist. can please give me direction?

does require specific on producer side?

the tutorials on rabbitmq website talk persistence in way if server die, messages persisted, or exemple 1 queue, n consummers, there persistency if consummers dead (becasue message not delivered), senario message delivered 1 of consummer (randomly), while need consummers receive messages subscribed to, , persistency per consummer.

thanks, rod

use topic exchange , have each consumer create it's own unique persistent queue , bind exchange topic want subscribe. publishing message on exchange deliver message each queue bound exchange/topic. if 1 of consumers dies, queue continue queue messages receives topic exchange.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
