java - Can multiple camel routes cause a very large number of threads? -


i clarify question.

i have task integrate 2 systems: frontend serving html , backend gives data frontend. backend have large rest api have use multiple routes. planned use single camel context , wrap routes it.

<camelcontext xmlns="http://activemq.apache.org/camel/schema/spring">     <from uri="direct:data"/>     <to uri="ahc:http://localhost/data"/>     <!--and on. more 70 routes--> </camelcontext>

then, planned invoke route using @produce annotation on service method adviced in hiding middleware article

public interface service {     string data(); }  public class mybean {     @produce(uri = "direct:data")     protected service producer;      public void dosomething() {         // lets send message         string response = producer.data();     } }

as understand information taken here , here i'll end additional 70 thread in app (one each route). fear can cause serious performance hit , while backend api grow thread number grow it. correct? how can avoid if it's true? understand, can't employ executorservice thread pool in case.

thanks in advance answer.

no not end thread per route. threading module tied threading model of consumer (eg route input).

for example route uses timer component use scheduled thread pool (1 thread). , jms component use 1 or more threads, depending on if set concurrentconsumers=n, etc.

the direct component direct method invocation , uses caller thread, there 0 new threads threading model.

if 70 routes uses ahc in < > may want re-use same endpoint, reuse thread pool of ahc library. or alternative configure shared pool used ahc endpoints.

and btw question posted on camel user forum / mailinglist: http://camel.465427.n5.nabble.com/can-multiple-camel-routes-cause-a-very-large-number-of-threads-tp5736620.html

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
