java - azure iothub device status -


getconnectionstate() connected /disconnected depending on device .if sending message should see connected , if not sending should disconnected .but each time run below java program getting status disconnected irrespective of device sending messages or not 

registrymanager registrymanager = registrymanager.createfromconnectionstring(connectionstring);     system.out.println(registrymanager.getdevices(new integer(1000)));     while(true){     arraylist<device> deviceslist=registrymanager.getdevices(new integer(1000));     for(device device:deviceslist)     {         /*system.out.println(device.getdeviceid());         system.out.println(device.getprimarykey());         system.out.println(device.getsecondarykey());*/         system.out.println(device.getdeviceid());         system.out.println(device.getconnectionstate());         /*system.out.println(device.getconnectionstateupdatedtime());         system.out.println(device.getlastactivitytime());         system.out.println(device.getstatusreason());         system.out.println(device.getstatusupdatedtime());         system.out.println(device.getsymmetrickey());         system.out.println(device.getetag()); */  }     }

i seeing otherwise.

i'm creating simple c# console application using code below,

    static async void querydevices()     {         registrymanager manager = registrymanager.createfromconnectionstring(connectionstring);         while (true)         {             var devices = await manager.getdevicesasync(100);             {                 foreach (var item in devices)                 {                     console.writeline(datetime.now + ": " + item.id + ", " + item.connectionstate);                      system.threading.thread.sleep(100);                 }             }         }     }

the git here query whole device list, because connectionstate property somehow looks "static" memebers of single device client instance, not apt-to change when actual state changes.

and output below, "connected" state when i'm using java client sample send message iot hub.

.net - Bulk insert via Dapper is slower than inserting rows one-by-one -

i'm using dapper insert data realtime feed sql server, care performance. recently, noticed strange. out of box, if give dapper collection , insert query, fires insert statements each element. tests show can insert 1800 objects 12 fields in 1 second way (counting connection.execute(...) running time. now, didn't find batch insert functionality in dapper , implemented own (constructing parameter list , sql query). after that, found out can insert 1 batch in 3 seconds (which limited 1000 rows) (again, counting connection.execute(...) calls. so, makes batching 6 times slower sending each row in separate query. can explain me? thought people use batch operations speed process. insert time 1 second @ most. use sql server 2012 standard on local network. table i'm inserting has clustered index on primary key (which bigint field), no non-clustered indexes , triggers. can post code, there's nothing special i'm not sure why using dapper execute extension ...
