azure service fabric - Increase timeout for RunAsync -

-

i creating number of service bus clients in runasync method on statefull service.

the method takes longer 4 seconds allowed when running in development environment , application fail start.

it fails because of appears latency between dev machine , azure.

i in thailand. azure in south central us.

can 4000 millisecond timeout increased locally on dev box?

the error is:

{  {    "message": "runasync has been cancelled stateful service replica. cancellation considered 'slow' if runasync not halt execution within 4000 milliseconds.           "level": "informational",   "keywords": "0x0000f00000000000",   "eventname": "statefulrunasynccancellation",   "payload": { [...] "slowcancellationtimemillis": 4000.0

} }

the problem not runasync takes long run, it's takes long cancel.

service fabric has default (hard-coded) timeout 4 seconds reporting "slow" cancellations. means after time produce health event (which may important during upgrades affects health status of entire application).

the real problem implementation of runasync. when remove service or upgrade one, service fabric wait (potentially forever) shut down gracefully. code should respect cancellationtoken passed runasync method. example, if have multiple io operations, call cancellationtoken.throwifcancellationrequested() after each 1 (whenever possible) , pass method accepts parameter.

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...
