azure - Why does it take so long to get through first level retries? -


i've started playing around nservicebus on azure, , reason takes long time through first level retries when message handler throws exception. retries set 5 takes 20+ minutes before second level retries kick in.

what causing delay?

here's how i'm configuring bus:

configure.transactions.advanced(s => {     s.disabledistributedtransactions();     s.donotwraphandlersexecutioninatransactionscope(); });  configure.with()     .autofacbuilder(container)     .definingcommandsas(t => t.iscommand())     .definingeventsas(t => t.isevent())     .xmlserializer()     .messageforwardingincaseoffault()     .azureconfigurationsource()     .usetransport<azurestoragequeue>()     .azurediagnosticslogger()                          .azuremessagequeue()                          .azuresubcriptionstorage()                          .useazuretimeoutpersister()      .unicastbus()                          .runhandlersunderincomingprincipal(false);

fyi: i'm using nservicebus built develop branch of today , running in emulator.

oh, misread question, thought taking 20 minutes after last retry second level kick in. know , it's configurable!

to support batching (to lower cost) message visible time calculated multiplying individual messageinvisibletime amount in batchsize, default messageinvisibletime 30000 (milliseconds), default batchsize 10. multiply again 5 first level retries , you'll end 25 minutes before first exception occurs , second level kick in.

you can reconfigure if like: messageinvisibletime , batchsize property on azurequeueconfig , maxretries sits on transportconfig (in 4.0) or msmqtransportconfig (in 3.x)
