Rabbitmq and catch all queue -

-

in company i'm running battery of tests running on different android devices.

today tests (that tasks) running in single queue multiple workers.

i want split single queue in multiple queue, 1 every device in order optimize tests launches according how many x devices company has (i.e. if company has 2 devices want send tests on devices in queue single worker --concurrency=2 can launch max 2 test in row).

i don't want migrate in time i'm taking first step implement hybrid version , logic i'd implement following.

device a (there 2 of them) , b (it's one) go on queue a , queue b while others in old legacy one.

enter image description here

my problem legacy queue. if send test on device c, sending task queue c, since catch_all queue named legacy task not received. i'm searching way say: "please rabbitmq use queue legacy if existing queue name not match device name".

there way achieve this?

you can combination of alternate exchange (https://www.rabbitmq.com/ae.html), , bindings routing keys

your setup have queuea , queueb bound through exchange, using binding key represents device. 

 | exchange| binding  | queue  | |---------|----------|--------| |  my.ex  | device.a | queuea | |  my.ex  | device.b | queueb |

when publish message device a, have routing key of device.a , go queuea.

now of legacy devices, set alternate exchange on exchange configuration. deliver messages don't match device.a or device.b routing keys, alternate exchange.

the alternate exchange route messages legacy queue.

Android volley - avoid multiple requests of the same kind to the server? -

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
